A few years ago, using Spark as a big data processing engine can be said to be very common or even natural. Since Spark can either perform batch processing or use micro-batch to simulate streaming, one engine solves both streaming and batch problems.
However, in recent years, with the development of big data technology, Flink, which is also a big data processing engine, has gradually entered people's vision and has occupied a certain market in the field of computing engines.
In the big data technology community, forums and other territories, the voice of whether Hudi supports Flink has gradually appeared and has become more frequent. Therefore, it is a valuable thing to make Hudi support the Flink engine, and the first step of integrating the Flink engine is that Hudi and Spark are decoupled.</p><p>In addition, looking at the mature, active, and viable frameworks in the big data, all frameworks are elegant in design and can be integrated with other framework [...]

While a stream processing pipeline does row-oriented processing, delivering a few seconds of processing latency, an incremental pipeline would apply the same principles to <em>columnar</em> data in the data lake,
delivering orders of magnitude improvements in processing efficiency within few minutes, on extremely scalable batch storage/compute infrastructure. This new stack would be able to effortlessly support regular batch processing for bulk reprocessing/backfilling as well.
Hudi was built as the manifestation of this vision, rooted in real, hard problems faced at <a href="https://eng.uber.com/uber-big-data-platform/" target="_blank" rel="noopener noreferrer">Uber</a> and later took a life of its own in the open source community. Together, we have been able to

Apache Hudi is often used in combination with kafka as a event stream where all events are transmitted according to a record schema.
In our case a Confluent schema registry is used to maintain the schema and as schema evolves, newer versions are updated in the schema registry.</p><h2 class="anchor anchorWithStickyNavbar_y2LR" id="what-do-we-want-to-achieve">What do we want to achieve?<a class="hash-link" href="#what-do-we-want-to-achieve" title="Direct link to heading"></a></h2><p>We have multiple instances of DeltaStreamer running, consuming many topics with different schemas ingesting to multiple Hudi tables.

Ideally every topic should be able to evolve the schema to match new business requirements. Producers start producing data with a new schema version and the DeltaStreamer picks up the new schema and ingests the data with the new schema. For this to work, we run our DeltaStreamer instances with the latest schema version available from the Schema Registry to ensure that we always use the freshest schema with all attributes.

The Deserializer then reads the records from the topic using the schema the record was written with. As next step it will convert all the records to the latest schema from the SchemaProvider, in our case the latest schema. As a result, the kafka client will return all records with a unified schema i.e. the latest schema as per schema registry.

As of today, to ingest data from S3 into Hudi, users leverage DFS source whose <a href="https://github.com/apache/hudi/blob/178767948e906f673d6d4a357c65c11bc574f619/hudi-utilities/src/main/java/org/apache/hudi/utilities/sources/helpers/DFSPathSelector.java" target="_blank" rel="noopener noreferrer">path selector</a> would identify the source files modified since the last checkpoint based on max modification time.
The problem with this approach is that modification time precision is upto seconds in S3. It maybe possible that there were many files (beyond what the configurable source limit allows) modifed in that second and some files might be skipped.

A few years ago, using Spark as a big data processing engine can be said to be very common or even natural. Since Spark can either perform batch processing or use micro-batch to simulate streaming, one engine solves both streaming and batch problems.
However, in recent years, with the development of big data technology, Flink, which is also a big data processing engine, has gradually entered people's vision and has occupied a certain market in the field of computing engines.
In the big data technology community, forums and other territories, the voice of whether Hudi supports Flink has gradually appeared and has become more frequent. Therefore, it is a valuable thing to make Hudi support the Flink engine, and the first step of integrating the Flink engine is that Hudi and Spark are decoupled.</p><p>In addition, looking at the mature, active, and viable frameworks in the big data, all frameworks are elegant in design and can be integrated with other framework [...]

While a stream processing pipeline does row-oriented processing, delivering a few seconds of processing latency, an incremental pipeline would apply the same principles to <em>columnar</em> data in the data lake,
delivering orders of magnitude improvements in processing efficiency within few minutes, on extremely scalable batch storage/compute infrastructure. This new stack would be able to effortlessly support regular batch processing for bulk reprocessing/backfilling as well.
Hudi was built as the manifestation of this vision, rooted in real, hard problems faced at <a href="https://eng.uber.com/uber-big-data-platform/" target="_blank" rel="noopener noreferrer">Uber</a> and later took a life of its own in the open source community. Together, we have been able to

Apache Hudi is often used in combination with kafka as a event stream where all events are transmitted according to a record schema.
In our case a Confluent schema registry is used to maintain the schema and as schema evolves, newer versions are updated in the schema registry.</p><h2 class="anchor anchorWithStickyNavbar_y2LR" id="what-do-we-want-to-achieve">What do we want to achieve?<a class="hash-link" href="#what-do-we-want-to-achieve" title="Direct link to heading"></a></h2><p>We have multiple instances of DeltaStreamer running, consuming many topics with different schemas ingesting to multiple Hudi tables.

Ideally every topic should be able to evolve the schema to match new business requirements. Producers start producing data with a new schema version and the DeltaStreamer picks up the new schema and ingests the data with the new schema. For this to work, we run our DeltaStreamer instances with the latest schema version available from the Schema Registry to ensure that we always use the freshest schema with all attributes.

The Deserializer then reads the records from the topic using the schema the record was written with. As next step it will convert all the records to the latest schema from the SchemaProvider, in our case the latest schema. As a result, the kafka client will return all records with a unified schema i.e. the latest schema as per schema registry.

Hudi adds per record metadata fields like <code>_hoodie_record_key</code>, <code>_hoodie_partition path</code>, <code>_hoodie_commit_time</code> which serves multiple purposes.
They assist in avoiding re-computing the record key, partition path during merges, compaction and other table operations

As of today, to ingest data from S3 into Hudi, users leverage DFS source whose <a href="https://github.com/apache/hudi/blob/178767948e906f673d6d4a357c65c11bc574f619/hudi-utilities/src/main/java/org/apache/hudi/utilities/sources/helpers/DFSPathSelector.java" target="_blank" rel="noopener noreferrer">path selector</a> would identify the source files modified since the last checkpoint based on max modification time.
The problem with this approach is that modification time precision is upto seconds in S3. It maybe possible that there were many files (beyond what the configurable source limit allows) modifed in that second and some files might be skipped.

making such a change and how it impacts current and new users. Any changes to such components affect the correctness of a dataset (backwards and forward versions supported).

Using primary keys, Hudi can impose a) partition level uniqueness integrity constraint b) enable fast updates and deletes on records.
One should choose the partitioning scheme wisely as it could be a determining factor for your ingestion and query latency.</p><p>In general, Hudi supports both partitioned and global indexes. For a dataset with partitioned index(which is most commonly used), each record is uniquely identified by a pair of record key and partition path.
But for a dataset with global index, each record is uniquely identified by just the record key. There won't be any duplicate record keys across partitions.</p><h2 class="anchor anchorWithStickyNavbar_y2LR" id="key-generators">Key Generators<a class="hash-link" href="#key-generators" title="Direct link to heading"></a></h2><p>Hudi provides several key generators out of the box that users can use based on their need, while having a pluggable

Metadata Table is to eliminate the requirement for the "list files" operation.</p><p>When reading and writing data, file listing operations are performed to get the current view of the file system.

like AWS S3, the large number of file listing requests sometimes causes throttling due to certain request limits.

while also efficiently supporting retrieval of data in the order of arrival. A Hudi instant consists of the following components</p><ul><li><code>Instant action</code> : Type of action performed on the table</li><li><code>Instant time</code> : Instant time is typically a timestamp (e.g: 20190117010349), which monotonically increases in the order of action's begin time.</li><li><code>state</code> : current state of the instant</li></ul><p>Hudi guarantees that the actions performed on [...]

with other background cleaning/compactions. One key observation to make is that the commit time indicates the <code>arrival time</code> of the data (10:20AM), while the actual data
organization reflects the actual time or <code>event time</code>, the data was intended for (hourly buckets from 07:00). These are two key concepts when reasoning about tradeoffs between latency and completeness of data.</p><p>When there is late arriving data (data intended for 9:00 arriving >1 hr late at 10:20), we can see the upsert producing new data into even older time buckets/folders.
With the help of the timeline, an incremental query attempting to get all new data that was committed successfully since 10:00 hours, is able to very efficiently consume
-only the changed files without say scanning all the time buckets > 07:00.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/hudi/tree/asf-site/website/versioned_docs/version-0.10.0/timeline.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_mS5F" aria-hidden="true"><g><pa [...]

Using primary keys, Hudi can impose a) partition level uniqueness integrity constraint b) enable fast updates and deletes on records.
One should choose the partitioning scheme wisely as it could be a determining factor for your ingestion and query latency.</p><p>In general, Hudi supports both partitioned and global indexes. For a dataset with partitioned index(which is most commonly used), each record is uniquely identified by a pair of record key and partition path.
But for a dataset with global index, each record is uniquely identified by just the record key. There won't be any duplicate record keys across partitions.</p><h2 class="anchor anchorWithStickyNavbar_y2LR" id="key-generators">Key Generators<a class="hash-link" href="#key-generators" title="Direct link to heading"></a></h2><p>Hudi provides several key generators out of the box that users can use based on their need, while having a pluggable

Metadata Table is to eliminate the requirement for the "list files" operation.</p><p>When reading and writing data, file listing operations are performed to get the current view of the file system.

like AWS S3, the large number of file listing requests sometimes causes throttling due to certain request limits.

while also efficiently supporting retrieval of data in the order of arrival. A Hudi instant consists of the following components</p><ul><li><code>Instant action</code> : Type of action performed on the table</li><li><code>Instant time</code> : Instant time is typically a timestamp (e.g: 20190117010349), which monotonically increases in the order of action's begin time.</li><li><code>state</code> : current state of the instant</li></ul><p>Hudi guarantees that the actions performed on [...]
in one of the following states</p><ul><li><code>REQUESTED</code> - Denotes an action has been scheduled, but has not initiated</li><li><code>INFLIGHT</code> - Denotes that the action is currently being performed</li><li><code>COMPLETED</code> - Denotes completion of an action on the timeline</li></ul><figure><img class="docimage" src="/cn/assets/images/hudi_timeline-bf5d8c5e59180434796d82af2b783e6c.png" alt="hudi_timeline.png"></figure><p>Example above shows upserts happenings between 10 [...]
with other background cleaning/compactions. One key observation to make is that the commit time indicates the <code>arrival time</code> of the data (10:20AM), while the actual data
organization reflects the actual time or <code>event time</code>, the data was intended for (hourly buckets from 07:00). These are two key concepts when reasoning about tradeoffs between latency and completeness of data.</p><p>When there is late arriving data (data intended for 9:00 arriving >1 hr late at 10:20), we can see the upsert producing new data into even older time buckets/folders.
With the help of the timeline, an incremental query attempting to get all new data that was committed successfully since 10:00 hours, is able to very efficiently consume
-only the changed files without say scanning all the time buckets > 07:00.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/hudi/tree/asf-site/website/versioned_docs/version-0.10.1/timeline.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_mS5F" aria-hidden="true"><g><pa [...]
