- Brings more order and cohesion to the classes in hudi-common
- Utils classes related to a particular concept (avro, timeline,...) are placed near to the package
- common.fs package now contains all the filesystem level classes including wrapper filesystem
- bloom.filter package renamed to just bloom
- config package contains classes that help store properties
- common.fs.inline package contains all the inline filesystem classes/impl
- common.table.timeline now consolidates all timeline related classes
- common.table.view consolidates all the classes related to filesystem view metadata
- common.table.timeline.versioning contains all classes related to versioning of timeline
- Fix few unit tests as a result
- Moved the test packages around to match the source file move
- Rename AvroUtils to TimelineMetadataUtils & minor fixes/typos
- Just package, class moves and renames with the following intent
- `client` now has all the various client classes, that do the transaction management
- `func` renamed to `execution` and some helpers moved to `client/utils`
- All compaction code under `io` now under `table/compact`
- Rollback code under `table/rollback` and in general all code for individual operations under `table`
- `exception` `config`, `metrics` left untouched
- Moved the tests also accordingly
- Fixed some flaky tests
- Upgrade Spark to 2.4.4, Parquet to 1.10.1, Avro to 1.8.2
- Remove spark-avro from hudi-spark-bundle. Users need to provide --packages org.apache.spark:spark-avro:2.4.4 when running spark-shell or spark-submit
- Replace com.databricks:spark-avro with org.apache.spark:spark-avro
- Shade avro in hudi-hadoop-mr-bundle to make sure it does not conflict with hive's avro version.
- Introduced configs for bloom filter type
- Implemented dynamic bloom filter with configurable max number of keys
- BloomFilterFactory abstractions; Defaults to current simple bloom filter
