+The Rust implementation of [Apache Arrow] has just released version `9.0.0`.
+
+While a major version of this magnitude may shock some in the Rust
+community to whom it implies a slow moving 20 year old piece of
+software, nothing could be further from the truth!
+
+With regular and predictable bi-weekly releases, the library continues
+to evolve and `9.0.0` is no exception. Some recent highlights
+
+
+# `parquet`: async, performance, safety and nested types
+
+The parquet `9.0.0` release includes an `async` reader (TODO link to rustdoc
+when published), a long time requested feature. Using the `async`
+reader it is now possible to read only the relevant parts of a parquet
+file from a networked source such as object storage. Previously the
+entire file had to be buffered locally. We are hoping to add a `async`
+writer in a future release and would love some
+[help](https://github.com/apache/arrow-rs/issues/1269).
+
+It is also significantly faster to read parquet data (up to
+[60x](https://github.com/apache/arrow-rs/pull/1180#issuecomment-1018518863)
+in some cases) than with previous versions of the `parquet`
+crate. Kudos to [tustvold](https://github.com/tustvold) and
+[yordan-pavlov](https://github.com/yordan-pavlov) for their
+contributions in these areas.

An update here is that we are still working out the 9.0 release -- once that is merged I'll update this page with the correct dates / doc links and plan to publish. Ideally that will happen sometime this weekend

+The Rust implementation of [Apache Arrow] has just released version `9.0.0`.
+
+While a major version of this magnitude may shock some in the Rust
+community to whom it implies a slow moving 20 year old piece of
+software, nothing could be further from the truth!
+
+With regular and predictable bi-weekly releases, the library continues
+to evolve and `9.0.0` is no exception. Some recent highlights
+
+
+# `parquet`: async, performance, safety and nested types
+
+The parquet `9.0.0` release includes an `async` reader (TODO link to rustdoc
+when published), a long time requested feature. Using the `async`
+reader it is now possible to read only the relevant parts of a parquet
+file from a networked source such as object storage. Previously the
+entire file had to be buffered locally. We are hoping to add a `async`

+in some cases) than with previous versions of the `parquet`
+crate. Kudos to [tustvold](https://github.com/tustvold) and
+[yordan-pavlov](https://github.com/yordan-pavlov) for their
+contributions in these areas.
+
+With `8.0.0` and later, the code that reads and writes `RecordBatch`es
+to and from Parquet now supports all types, including deeply nested
+structs and lists. Thanks [helgikrs](https://github.com/helgikrs) for
+cleaning up the last corner cases!
+
+Other notable recent additions to parquet are `UTF-8` validation on
+string data for improved security against malicious inputs.
+
+Planned upcoming work includes [pushing more
+filtering](https://github.com/apache/arrow-rs/issues/1191) directly
+into the parquet scan as well as an `async` writer.
+
+
+# `arrow`: performance, dyn kernels, and DecimalArray
+
+The [compute](https://docs.rs/arrow/latest/arrow/compute/index.html)
+kernels have been improved significantly in arrow `9.0.0`. Some [filter
+benchmarks](https://github.com/apache/arrow-rs/pull/1228#issue-1111889246)
+are twice as fast and the SIMD kernels are also [significantly
+faster](https://github.com/apache/arrow-rs/pull/1221). Many thanks to tustvold
+[tustvold](https://github.com/tustvold) and
+[jhorstmann](https://github.com/jhorstmann).
+[Additional substantial](https://github.com/apache/arrow-rs/pull/1248)
+improvements are likely to land in arrow `10.0.0`.
+
+We are working on new set of "dynamic" `dyn_` kernels (for example,
+[`eq_dyn`](https://docs.rs/arrow/8.0.0/arrow/compute/kernels/comparison/fn.eq_dyn.html))
+that make it easier to invoke the heavily optimized kernels provided
+by the `arrow` crate. Work is underway to expand the breadth of types
+supported by these new kernels to make them even more useful. Thanks
+to [matthewmturner](https://github.com/matthewmturner) and
+[viirya](https://github.com/viirya) for their help in this
+effort.
+
+While `arrow` has had basic support for `DecimalArray` since version
+`3.0.0`, support has been expanded for `Decimal` type in calculation
+kernels such as `sort`, `take` and `filter` thanks to some great
+contributions from [liukun4515](https://github.com/liukun4515). There
+is [ongoing work](https://github.com/apache/arrow-rs/pull/1223) to
+improve the API ergonomics and performance of `DecimalArray` as well.
+
+# Security
+
+The `6.4.0` release resolved the last outstanding
+[RUSTSEC](https://rustsec.org/)
+[advisory](https://github.com/rustsec/advisory-db/pull/1131) on the
+arrow crate and the `8.0.0` release resolved the last outstanding
+known security issues. While these security issues were mostly limited
+misuse of the low level "power user" APIs which most users do not (and
+should not) be using, it is good to tighten up that area.
+
+Now that `arrow-rs` is releasing major versions every other week, we
+are also able to update dependencies at the same pace, helping to
+ensure that security fixes upstream can flow more quickly to
+downstream projects.
+
+# Final shoutout
+It takes a community to build great software, and we would like to
+thank everyone who has contributed to the arrow-rs repository since
+the `7.0.0` release:

Review comment:
This is of course well outside the scope of this blogpost, so not at all suggesting that it needs to be added here. But I wanted to draw your attention to https://lists.apache.org/thread/n98tr38moqvbf1rlqd7n7912mfrqv8ps in case you missed it. I know there was some desire to get Rust benchmarks running in conbench and with Elena's work there that _should_ be possible now (just need to add a machine to run them + a PR to that repo). Elena and I are happy to help with parts of that if we can.
On the R and Python libraries, we've found it super useful for tracking benchmarks like these (and being able to link to them publicly)

+The Rust implementation of [Apache Arrow] has just released version `9.0.0`.
+
+While a major version of this magnitude may shock some in the Rust
+community to whom it implies a slow moving 20 year old piece of
+software, nothing could be further from the truth!
+
+With regular and predictable bi-weekly releases, the library continues
+to evolve and `9.0.0` is no exception. Some recent highlights
+
+
+# `parquet`: async, performance, safety and nested types
+
+The parquet `9.0.0` release includes an `async` reader (TODO link to rustdoc
+when published), a long time requested feature. Using the `async`
+reader it is now possible to read only the relevant parts of a parquet
+file from a networked source such as object storage. Previously the
+entire file had to be buffered locally. We are hoping to add a `async`
+writer in a future release and would love some
+[help](https://github.com/apache/arrow-rs/issues/1269).
+
+It is also significantly faster to read parquet data (up to
+[60x](https://github.com/apache/arrow-rs/pull/1180#issuecomment-1018518863)
+in some cases) than with previous versions of the `parquet`
+crate. Kudos to [tustvold](https://github.com/tustvold) and
+[yordan-pavlov](https://github.com/yordan-pavlov) for their
+contributions in these areas.
Review comment:
As a starting point, I am hoping to add 8 Raspberry Pi nodes shortly. I am considering adding some more powerful hardware as well, perhaps a Mac Mini.
