This release contains significant format changes and new exciting features +as we will see below. + +## Migration Guide + +We encourage users to try the **1.0.0** features on new tables first. The 1.0 general availability (GA) release will +support automatic table upgrades from 0.x versions while also ensuring full backward compatibility when reading 0.x +Hudi tables using 1.0, ensuring a seamless migration experience. + +This release comes with **backward compatible writes** i.e. 1.0.0 can write in both the table version 8 (latest) and older +table version 6 (corresponds to 0.14 & above) formats. Automatic upgrades for tables from 0.x versions are fully +supported, minimizing migration challenges. Until all the readers are upgraded, users can still deploy 1.0.0 binaries +for the writers and leverage backward compatible writes to continue writing the tables in the older format. Once the readers +are fully upgraded, users can switch to the latest format through a config change. We recommend users to follow the upgrade +steps mentioned in the [migration guide](/docs/deployment#upgrading-to-100) to ensure a smooth transition. + +:::caution +Most things are seamlessly handled by the auto upgrade process, but there are some limitations. Please read through the +limitations of the upgrade downgrade process before proceeding to migrate. Please check the [migration guide](/docs/deployment#upgrading-to-100) +and [RFC-78](https://github.com/apache/hudi/blob/master/rfc/rfc-78/rfc-78.md#support-matrix-for-different-readers-and-writers) for more details. +::: + +## Bundle Updates + +- Same bundles supported in the [0.15.0 release](release-0.15#new-spark-bundles) are still supported. +- New Flink Bundles to support Flink 1.19 and Flink 1.20. +- In this release, we have deprecated support for Spark 3.2 or lower version in Spark 3. + +## Highlights + +### Format changes + +The main epic covering all the format changes is [this GitHub issue](https://github.com/apache/hudi/issues/15964), which is also covered in the [Hudi 1.0 tech specification](/learn/tech-specs-1point0). The following are the main highlights with respect to format changes: + +#### Timeline + +- The active and archived timeline dichotomy has been done away with a more scalable LSM tree based + timeline. The timeline layout is now more organized and efficient for time-range queries and scaling to infinite history. +- As a result, timeline layout has been changed, and it has been moved to `.hoodie/timeline` directory under the base + path of the table. +- There are changes to the timeline instant files as well: + - All commit metadata is serialized to Avro, allowing for future compatibility and uniformity in metadata across all + actions. + - Instant files for completed actions now include a completion time. + - Action for the pending clustering instant is now renamed to `clustering` to make it distinct from other + `replacecommit` actions. + +#### Log File Format + +- In addition to the keys in the log file header, we also store record positions. Refer to the + latest [spec](/learn/tech-specs-1point0#log-format) for more details. This allows us to do position-based merging (apart + from key-based merging) and skip pages based on positions. +- Log file name will now have the deltacommit instant time instead of base commit instant time. +- The new log file format also enables fast partial updates with low storage overhead. + +### Compatibility with Old Formats + +- **Backward Compatible writes:** Hudi 1.0 writes now support writing in both the table version 8 (latest) and older table version 6 (corresponds to 0.14 & above) formats, ensuring seamless + integration with existing setups. +- **Automatic upgrades**: for tables from 0.x versions are fully supported, minimizing migration challenges. We also recommend users first try migrating to 0.14 & + above, if you have advanced setups with multiple readers/writers/table services. + +### Concurrency Control + +1.0.0 introduces **Non-Blocking Concurrency Control (NBCC)**, enabling multi-stream concurrent ingestion without +conflict. This is a general-purpose concurrency model aimed at the stream processing or high-contention/frequent writing +scenarios. In contrast to Optimistic Concurrency Control, where writers abort the transaction if there is a hint of +contention, this innovation allows multiple streaming writes to the same Hudi table without any overhead of conflict +resolution, while keeping the semantics of event-time ordering found in streaming systems, along with asynchronous table +service such as compaction, archiving and cleaning. + +To learn more about NBCC, refer to [this blog](/blog/2024/12/06/non-blocking-concurrency-control) which also includes a demo with Flink writers. + +### New Indices + +1.0.0 introduces new indices to the multi-modal indexing subsystem of Apache Hudi. These indices are designed to improve +query performance through partition pruning and further data skipping. + +#### Secondary Index + +The **secondary index** allows users to create indexes on columns that are not part of record key columns in Hudi +tables. It can be used to speed up queries with predicates on columns other than record key columns. + +#### Partition Stats Index + +The **partition stats index** aggregates statistics at the partition level for the columns for which it is enabled. This +helps in efficient partition pruning even for non-partition fields. + +#### Expression Index + +The **expression index** enables efficient queries on columns derived from expressions. It can collect stats on columns +derived from expressions without materializing them, and can be used to speed up queries with filters containing such +expressions. + +To learn more about these indices, refer to the [SQL queries](/docs/sql_queries#snapshot-query-with-index-acceleration) docs. + +### Partial Updates + +1.0.0 extends support for partial updates to Merge-on-Read tables, which allows users to update only a subset of columns +in a record. This feature is useful when users want to update only a few columns in a record without rewriting the +entire record. + +To learn more about partial updates, refer to the [SQL DML](/docs/sql_dml#merge-into-partial-update) docs. + +### Multiple Base File Formats in a single table + +- Support for multiple base file formats (e.g., **Parquet**, **ORC**, **HFile**) within a single Hudi table, allowing + tailored formats for specific use cases like indexing and ML applications. +- It is also useful when users want to switch from one file + format to another, e.g. from ORC to Parquet, without rewriting the whole table. +- **Configuration:** Enable with `hoodie.table.multiple.base.file.formats.enable`. + +To learn more about the format changes, refer to the [Hudi 1.0 tech specification](/learn/tech-specs-1point0). + +### API Changes + +1.0.0 introduces several API changes, including: + +#### Record Merger API + +`HoodieRecordPayload` interface is deprecated in favor of the new `HoodieRecordMerger` interface. Record merger is a +generic interface that allows users to define custom logic for merging base file and log file records. This release +comes with a few out-of-the-box merge modes, which define how the base and log files are ordered in a file slice and +further how different records with the same record key within that file slice are merged consistently to produce the +same deterministic results for snapshot queries, writers and table services. Specifically, there are three merge modes +supported as a table-level configuration: + +- `COMMIT_TIME_ORDERING`: Merging simply picks the record belonging to the latest write (commit time) as the merged + result. +- `EVENT_TIME_ORDERING`: Merging picks the record with the highest value on a user specified ordering or precombine + field as the merged result. +- `CUSTOM`: Users can provide custom merger implementation to have better control over the merge logic. + +:::note +Going forward, we recommend users to migrate and use the record merger APIs and not write new payload implementations. +::: + +#### Positional Merging with Filegroup Reader + +- **Position-Based Merging:** Offers an alternative to key-based merging, allowing for page skipping based on record + positions. Enabled by default for Spark and Hive. +- **Configuration:** Activate positional merging using `hoodie.merge.use.record.positions=true`. + +The new reader has shown impressive performance gains for **partial updates** with key-based merging. For a MOR table of +size 1TB with 100 partitions and 80% random updates in subsequent commits, the new reader is **5.7x faster** for +snapshot queries with **70x reduced write amplification**. + +### Flink Enhancements + +- **Lookup Joins:** Flink now supports lookup joins, enabling table enrichment with external data sources. +- **Partition Stats Index Support:** As mentioned above, partition stats support is now available for Flink, bringing + efficient partition pruning to streaming workloads. +- **Non-Blocking Concurrency Control:** NBCC is now available for Flink streaming writers, allowing for multi-stream + concurrent ingestion without conflict. + +## Call to Action + +The 1.0.0 GA release is the culmination of extensive development, testing, and feedback. We invite you to upgrade and +experience the new features and enhancements. + +## Known Regressions +- We discovered a regression in Hudi 1.0.0 release for backwards compatible writer for MOR table. + It can silently deletes committed data after upgrade when new data is ingested to the table. +- We also have a ComplexKeyGenerator related regression reported [here](release-0.14#known-regressions). Please refrain from migrating, if you have single field as record key and multiple fields as partition fields.
