+
+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.

+
+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rs | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.
+
+
+[sdf-jkl](https://github.com/sdf-jkl), [liamzwbao](https://github.com/liamzwbao),
+[friendlymatthew](https://github.com/friendlymatthew), and
+[klion26](https://github.com/klion26) helped drive early Variant
+functionality in the Rust Parquet implementation and contributed a number
+of follow-up improvements.
+
+[jecsand838](https://github.com/jecsand838) drove major improvements to the
+Rust `arrow-avro` crate, work highlighted in the
+[Introducing Arrow Avro](https://arrow.apache.org/blog/2025/10/23/introducing-arrow-avro/)
+blog post.

+| hamilton-earthscope | 5 | 2998 |
+
+
+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.
+
+Moving some implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current apache/arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache/ repos namely
+[apache/arrow-java](https://github.com/apache/arrow-java),
+[apache/arrow-js](https://github.com/apache/arrow-js),
+[apache/arrow-rs](https://github.com/apache/arrow-rs),
+[apache/arrow-go](https://github.com/apache/arrow-go),
+[apache/arrow-nanoarrow](https://github.com/apache/arrow-nanoarrow),
+[apache/arrow-dotnet](https://github.com/apache/arrow-dotnet) and
+[apache/arrow-swift](https://github.com/apache/arrow-swift).
+
+#### Notable Contributors in apache/arrow for 2025 are:
+
+| Author | # of prs | # of line changes (+ and -) |
+|---|---|---|
+| kou | 221 | 141015 |
+| AntoinePrv | 8 | 79257 |
+| raulcd | 110 | 46645 |
+| pitrou | 101 | 36585 |
+| jbonofre | 1 | 20061 |
+
+
+#### Notable Components in apache/arrow for 2025 are:
+
+| Component label | # of merged prs | # of line changes (+ and -) |
+|---|---|---|
+| Parquet | 100 | 103828 |
+| C++ | 387 | 82744 |
+| FlightRPC | 43 | 52659 |
+| CI | 237 | 42249 |
+| Ruby | 74 | 20676 |
+
+
+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wound down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to an Arrow-managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^3]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^4], [^5]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+The biggest changes in apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to the Java
+implementation being moved into a separate Apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in the
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).
+
+Noticeable emphasis was also visible on performance-focused PRs leading to
+the addition of row seeking, bloom filter reading/writing, and reduction of
+allocations in the Parquet library along with significant optimization work
+in the ``compute.Take` kernels. Shout out to [pixelherodev](https://github.com/pixelherodev)
+and [hamilton-earthscope](https://github.com/hamilton-earthscope) for the
+emphasis they placed on improving performance.
+
+### Nanoarrow
+
+Bigger work in nanoarrow include Decimal32/64 and ListView/LargeListView support,
+LZ4 and ZSTD decompression in the IPC reader, and broader packaging via Conan, Homebrew,
+and vcpkg. Contributors driving most above are [paleolimbot](https://github.com/paleolimbot)
+and [WillAyd](https://github.com/WillAyd).

+Moving last implementations out of the main repository (apache/arrow on GitHub)
Review Comment:
"some" implementations perhaps, "last" is a bit weird given the main repo still hosts C++ and relatives.

+It has been great to see many new contributors joining the project
+in the past year with over 300 such individuals observed in main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and

+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd).
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.
+
+Moving last implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache repos namely apache/arrow-java,
+apache/arrow-js, apache/arrow-rs, apache/arrow-go, apache/arrow-dotnet and apache/arrow-swift.

+
+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.

+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).

+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^3]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^4], [^5]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+The biggest changes in apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to the Java
+implementation being moved into a separate Apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in the
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).
+
Review Comment:
There's also been a noticeable emphasis on performance-focused PRs leading to the addition of row seeking, bloom filter reading/writing, and reduction of allocations in the parquet library along with significant optimization work in the compute.Take kernels. Shout out to [pixelherodev](https://github.com/pixelherodev] and [hamilton-earthscope](https://github.com/hamilton-earthscope) for the emphasis they placed on improving performance

Thank you all for the reviews and comments, much appreciated!
I think I included them all. I have also updated the notebooks (no #comments and #reviews columns, nanoarrow notebook has been added).

+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+Biggest changes apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to Java
+implementation being moved into a separate apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).

+
+## Arrow Summit 25
+
+One last thing to highlight would be our first Arrow Summit 25 that
+was held in Paris in October 2025. The event was a great success and
+it brought users, contributors and maintainers together. It
+definitely was a highlight of the year for many of us. Thanks to
+[raulcd](https://github.com/raulcd) and [pitrou](https://github.com/pitrou)
+for organizing the event.

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.
+
+Moving some implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current apache/arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache/ repos namely
+[apache/arrow-java](https://github.com/apache/arrow-java),
+[apache/arrow-js](https://github.com/apache/arrow-js),
+[apache/arrow-rs](https://github.com/apache/arrow-rs),
+[apache/arrow-go](https://github.com/apache/arrow-go),

+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is lead by [pitrou](https://github.com/pitrou)

+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).

+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by

+implementation being moved into a separate apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).

+
+## Arrow Summit 25
+
+One last thing to highlight would be our first Arrow Summit 25 that
+was held in Paris in October 2025. The event was a great success and
+it brought users, contributors and maintainers together. It
+definitely was a highlight of the year for many of us. Thanks to
+[raulcd](https://github.com/raulcd) and [pitrou](https://github.com/pitrou)
+for organizing the event.

+#### Notable Components in apache/arrow for 2025 are:
+
+| Component label | # of merged prs | # of line changes (+ and -) |
+|---|---|---|
+| Parquet | 100 | 103828 |
+| C++ | 387 | 82744 |
+| FlightRPC | 43 | 52659 |
+| CI | 237 | 42249 |
+| Ruby | 74 | 20676 |
+
+
+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+Biggest changes apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to Java
+implementation being moved into a separate apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).
+
+---
+
+## Arrow Summit 25
+
+One last thing to highlight would be our first Arrow Summit 25 that
+was held in Paris in October 2025. The event was a great success and
+it brought users, contributors and maintainers together. It
+definitely was a highlight of the year for many of us. Thanks to
+[raulcd](https://github.com/raulcd) and [pitrou](https://github.com/pitrou)
+for organizing the event.

+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.
+
+---
+
+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd).
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.
Review Comment:
Link to the Archery docs? Otherwise it might be cryptic to the reader.

Review Comment:
Yes, that might be true. My general feeling in the apache repos is that bigger and important prs get more reviews and comments. But will trust you on this!
I have already removed the columns from the blog post. Will also see if removing them from the ranking in the notebooks changes anything and will update accordingly.

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.

Review Comment:
maybe just `custom made linting tools` without specifying archery?

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year with over 300 such individuals observed in main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+Notable contributions worth mentioning are enhanced release automation and

+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.
+
+Moving last implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache repos namely apache/arrow-java,
+apache/arrow-js, apache/arrow-rs, apache/arrow-go, apache/arrow-dotnet and apache/arrow-swift.

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is lead by [pitrou](https://github.com/pitrou)
+who is also the most active member of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical

Review Comment:
You are right I need to take a better look at this numbers. What I actually counted, though, are number of comments and number of reviews (that would probably mean number of comments as part of reviews) for the PRs the user authored. I wanted to get a better picture of the importance of the merged PRs and thought that bigger contributions include higher amount of comments and reviews.
Will double check anyways and remove the columns from the blog post. They can be viewed in the linked notebooks for reference anyways.

Review Comment:
Love this! Had a mini rework to suggest for the opener, but it's good as it is so not necessary to integrate.
> As you may have read in a previous blog post, the Apache Arrow project recently turned 10 years old. We are grateful to everyone who helped us achieve this milestone, and we wanted to celebrate the community's accomplishments, by publishing our community highlights from 2025.
>
> We were inspired by the research by Dr Cat Hicks et al [^1], who found that concrete evidence of progress and accomplishments is instrumental to motivation and collaboration in open source.

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.
+
+Moving some implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current apache/arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+Biggest changes apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to Java
Review Comment:
```suggestion

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+Biggest changes apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to Java
+implementation being moved into a separate apache repository.
Review Comment:
```suggestion
implementation being moved into a separate Apache repository.

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year with over 300 such individuals observed in main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd).
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.
+
+Moving last implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache repos namely apache/arrow-java,
+apache/arrow-js, apache/arrow-rs, apache/arrow-go, apache/arrow-dotnet and apache/arrow-swift.

+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.

how did you compute these? Can we compute them for arrow-go also? :smile: specifically the `arrow`, `parquet`, and `internal` components

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year with over 300 such individuals observed in main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+
+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd).
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.
+
+Moving last implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache repos namely apache/arrow-java,
+apache/arrow-js, apache/arrow-rs, apache/arrow-go, apache/arrow-dotnet and apache/arrow-swift.

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is lead by [pitrou](https://github.com/pitrou)
+who is also the most active member of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical

There was a detailed blog post somewhere about this (perhaps on the Hugging Face blog?), perhaps link to it?

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wound down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to an Arrow-managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^3]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^4], [^5]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).

+
+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.

Review Comment:
I look through merged PRs and group by labels (if used) and title prefix/commit style type. For Go this was a bit harder to do as the labels are not used for the components, most of the information I got from the commits, see: https://github.com/arrow-maintenance/explorations/blob/main/yearly_highlights/github_repo_report_arrow_go.ipynb.
The current output would thus be:

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wind down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to Arrow managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^2]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^3], [^4]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+Biggest changes apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to Java
+implementation being moved into a separate apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).
+

+
+## Arrow Summit 25
+
+One last thing to highlight would be our first Arrow Summit 25 that
+was held in Paris in October 2025. The event was a great success and
+it brought users, contributors and maintainers together. It
+definitely was a highlight of the year for many of us. Thanks to
+[raulcd](https://github.com/raulcd) and [pitrou](https://github.com/pitrou)
+for organizing the event.

+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year with over 300 such individuals observed in main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |

+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the

+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,

+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd).
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom archery linting.

+
+As you may have read in a previous blog post [^1], the Apache Arrow project
+recently turned 10 years old. We are grateful to everyone who helped us
+achieve this milestone, and we wanted to celebrate the community's
+accomplishments, by publishing our community highlights from 2025.
+
+We were inspired by the research by Dr Cat Hicks et al [^2], who found
+that concrete evidence of progress and accomplishments is instrumental
+to motivation and collaboration in developer teams. We think the same
+should hold for open source.

+
+## New contributors
+
+It has been great to see many new contributors joining the project
+in the past year, with over 300 such individuals observed across the main
+Apache Arrow language implementations.
+
+| Repository/Implementation | Number of new contributors |
+|---|---|
+| arrow | 125 |
+| arrow-rust | 131 |
+| arrow-java | 28 |
+| arrow-go | 35 |
+<br>
+
+Worth highlighting is [alinaliBQ](https://github.com/alinaliBQ) who
+has been very active on the C++ Flight SQL ODBC Driver work together
+with [justing-bq](https://github.com/justing-bq) .
+
+[AntoinePrv](https://github.com/AntoinePrv) has done huge amount of
+work on the C++ Parquet implementation and [andishgar](https://github.com/andishgar)
+in the C++ Statistics area.
+
+[rmnskb](https://github.com/rmnskb) got involved with PyArrow in
+EuroPython sprints and has contributed multiple PRs since then. On the
+same event [paddyroddy](https://github.com/paddyroddy) also started with
+his first contribution and helped on the Python packaging side further on.

+
+
+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.
+
+Moving some implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current apache/arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache/ repos namely
+[apache/arrow-java](https://github.com/apache/arrow-java),
+[apache/arrow-js](https://github.com/apache/arrow-js),
+[apache/arrow-rs](https://github.com/apache/arrow-rs),
+[apache/arrow-go](https://github.com/apache/arrow-go),
+[apache/arrow-nanoarrow](https://github.com/apache/arrow-nanoarrow),
+[apache/arrow-dotnet](https://github.com/apache/arrow-dotnet) and
+[apache/arrow-swift](https://github.com/apache/arrow-swift).
+

+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wound down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to an Arrow-managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^3]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^4], [^5]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+The biggest changes in apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to the Java
+implementation being moved into a separate Apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in the
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).

+
+## Release, Packaging and CI
+
+A lot of work has been done around the Continuous Integration and
+Developer Tools area. Ensuring a project with the reach of Arrow is properly working
+requires validation on a huge matrix of operating systems, architectures, libraries,
+versions. Needless to say that maintenance work has tremendous importance for the
+health of the project and the positive contributor experience.
+
+The most active contributors in the main repository are the ones contributing
+heavily on those areas while also providing the most review capacity. Shout out
+to [kou](https://github.com/kou) and [raulcd](https://github.com/raulcd) for
+taking such good care of the project and devoting countless hours so that everything
+runs smoothly.
+
+Notable contributions worth mentioning are enhanced release automation and
+reproducible builds for sources, migrating remaining AppVeyor and Azure jobs
+to GitHub actions, improving dev experience with more pre-commit checks instead
+of custom made linting tools.
+
+Moving some implementations out of the main repository (apache/arrow on GitHub)
+helped with easier releases and maintenance of the main repository and also of
+separate language implementations. The current apache/arrow repo now holds the format
+specification, C++ implementation together with all the bindings to it (Python, R, Ruby
+and C GLib). Other languages now live in their own apache/ repos namely
+[apache/arrow-java](https://github.com/apache/arrow-java),
+[apache/arrow-js](https://github.com/apache/arrow-js),
+[apache/arrow-rs](https://github.com/apache/arrow-rs),
+[apache/arrow-go](https://github.com/apache/arrow-go),
+[apache/arrow-nanoarrow](https://github.com/apache/arrow-nanoarrow),
+[apache/arrow-dotnet](https://github.com/apache/arrow-dotnet) and
+[apache/arrow-swift](https://github.com/apache/arrow-swift).

+
+## Migration of infrastructure from Voltron Data
+
+As Voltron Data has wound down its operations in 2025, the Arrow project
+had to migrate benchmarking infrastructure and nightly report from
+Voltron-managed services to an Arrow-managed AWS account. This work has been
+driven by [rok](https://github.com/rok).
+
+## Closing of Stale issues
+
+[thisisnic](https://github.com/thisisnic) was working on closing of stale
+issues in the apache/arrow repository which helped surfacing important
+issues that were overlooked or forgotten.
+
+## Code contributions
+
+### C++ implementation
+
+Community support for maintenance and development of the Acero C++
+is continuing with multiple bigger contributions in 2025 done by
+[pitrou](https://github.com/pitrou) and [zanmato1984](https://github.com/zanmato1984).
+
+Many kernels have been moved from the integrated compute module into
+a separate, optional package for improvement of modularity and distribution
+size when optional compute functionality is not being used. The work has
+been done by [raulcd](https://github.com/raulcd).
+
+### Arrow C++ Parquet implementation
+
+There have been multiple contributions to fix and improve fuzzing
+support for Parquet. Fuzzing work is led by [pitrou](https://github.com/pitrou)
+who is also one of the most active members of the community guiding other
+developers and supporting us with abundant review capacity.
+
+Multiple newer types have also been supported in the last year,
+namely: VARIANT, UUID, GEOMETRY and GEOGRAPHY contributed
+by [neilechao](https://github.com/neilechao) and
+[paleolimbot](https://github.com/paleolimbot).
+
+An important feature added has also been Content-Defined Chunking
+which improves deduplication of Parquet files with mostly identical
+contents, by choosing data page boundaries based on actual contents
+rather than a number of values [^3]. This work has been done by
+[kszucs](https://github.com/kszucs).
+
+There have been improvements in the Parquet encryption support for
+most of the releases in the last year. These efforts have been
+driven mostly by [EnricoMi](https://github.com/EnricoMi),
+[pitrou](https://github.com/pitrou), [adamreeve](https://github.com/adamreeve)
+and [kapoisu](https://github.com/kapoisu).
+
+### PyArrow
+
+A lot of work has been put into adding type annotations. It all
+started in July at EuroPython sprints and the code is now ready to be
+reviewed and merged. Some more review capacity will be needed to get
+this over the finish line. The work has been championed by
+[rok](https://github.com/rok).
+
+### Rust
+
+Arrow Rust community invested heavily in the Rust parquet reader for
+which they created several blog posts [^4], [^5]. The work has been
+championed by [alamb](https://github.com/alamb) and
+[etseidl](https://github.com/etseidl).
+
+#### Notable Components in apache/arrow-rs for 2025 are:
+
+| component | merged_prs | line_changes |
+|---|---|---|
+| parquet | 333 | 140958 |
+| arrow | 436 | 76590 |
+| parquet-variant | 125 | 41832 |
+| api-change | 59 | 33938 |
+| arrow-avro | 48 | 29487 |
+
+### Java
+
+The biggest changes in apache/arrow-java for 2025 have been connected
+to Flight and Avro components plus Sphinx support due to the Java
+implementation being moved into a separate Apache repository.
+Contributors involved in the above are [lidavidm](https://github.com/lidavidm)
+and [martin-traverse](https://github.com/martin-traverse).
+
+### Go
+
+There has been a lot of work related to new variant type in the
+Parquet implementation done in apache/arrow-go all by
+[zeroshade](https://github.com/zeroshade).
+
+Noticeable emphasis was also visible on performance-focused PRs leading to
+the addition of row seeking, bloom filter reading/writing, and reduction of
+allocations in the Parquet library along with significant optimization work
+in the ``compute.Take` kernels. Shout out to [pixelherodev](https://github.com/pixelherodev)
+and [hamilton-earthscope](https://github.com/hamilton-earthscope) for the
+emphasis they placed on improving performance.
+
+### Nanoarrow
+
+Bigger work in nanoarrow include Decimal32/64 and ListView/LargeListView support,
+LZ4 and ZSTD decompression in the IPC reader, and broader packaging via Conan, Homebrew,
+and vcpkg. Contributors driving most above are [paleolimbot](https://github.com/paleolimbot)
+and [WillAyd](https://github.com/WillAyd).

@paleolimbot does this sound right?

Review Comment:
@thisisnic I am thinking to add a minor change at the end of the last sentence:
> [...], who found that concrete evidence of progress and accomplishments is instrumental
to motivation and collaboration in developer teams. We think the same should hold for open source.
What do you think?

Review Comment:
It seems "# of pr reviews" is actually counting the number of PR review comments by others? I'm not sure that's relevant, but the column heading is misleading anyway (I don't think AntoinePrv did 300 PR reviews for example :-)).
(also, "# of comments on prs" counts comment by others on the author's PRs, so may be misleading as well)

Review Comment:
At least for reviews, "# number of reviewed prs" would be more informative IMHO.
