Migration Guide​

  • This release (1.0.2) does not introduce any new table version, thus no migration is needed if you are on 1.0.1.

Bug fixes​

The 1.0.2 release primarily focuses on bug fixes, stability enhancements, and critical improvements, particularly around migration and backwards compatibility. The changes span across various components, including:

  • Metadata Table (MDT): Numerous fixes and improvements related to validation, writing, reading, compaction, indexing (column stats), and backwards compatibility (especially for table version 6).
  • Spark Integration: Enhancements and fixes for Spark SQL (MERGE INTO, query behavior), datasource reader/writer, schema handling, performance, and backward compatibility.
  • Backwards Compatibility: Significant effort ensuring compatibility with older table versions (specifically v6) and smoother upgrades from 0.x versions, including dedicated writers/readers.
  • File Group Reader: Validation, fixes, and feature completeness improvements, including making it default for table version 6.
  • Flink Engine: Fixes and improvements related to streamer checkpoints and bundle validation.
  • Compaction and Table Services: Fixes related to compaction scheduling, execution (especially with global index or RLI), archival, and cleanup.
  • Indexing: Fixes and enhancements for Column Stats, Record Level Index (RLI), and Bloom Filters.
  • Performance: Optimizations in areas like log file writing, schema reuse, and metadata initialization.
  • Testing, CI, and Dependencies: Fixes for flaky tests, improved code coverage, bundle validation, dependency cleanup (HBase removal), and extensive release testing.
