Actually method FlinkWriteHelper#deduplicateRecords does not guarantee the records sequence, but there is a
implicit constraint: all the records in one bucket should have the same bucket type(instant time here),
the BucketStreamWriteFunction breaks the rule and fails to comply with this constraint.
closeapache/hudi#5018
* Fixed metadata conversion util to extract schema from `HoodieCommitMetadata`
* Fixed failure to fetch columns to index in empty table
* Abort indexing seq in case there are no columns to index
* Fallback to index at least primary key columns, in case no writer schema could be obtained to index all columns
* Fixed `getRecordFields` incorrectly ignoring default value
* Make sure Hudi metadata fields are also indexed
Refactoring Spark DataSource Relations to avoid code duplication.
Following Relations were in scope:
- BaseFileOnlyViewRelation
- MergeOnReadSnapshotRelaation
- MergeOnReadIncrementalRelation
- Adopt HoodieData in Spark action commit executors
- Make Spark independent DeleteHelper, WriteHelper, MergeHelper in hudi-client-common
- Make HoodieTable in WriteClient APIs have raw type to decouple with Client's generic types
NOTE: This change is first part of the series to clean up Hudi's Spark DataSource related implementations, making sure there's minimal code duplication among them, implementations are consistent and performant
This PR is making sure that BaseFileOnlyViewRelation only reads projected columns as well as avoiding unnecessary serde from Row to InternalRow
Brief change log
- Introduced HoodieBaseRDD as a base for all custom RDD impls
- Extracted common fields/methods to HoodieBaseRelation
- Cleaned up and streamlined HoodieBaseFileViewOnlyRelation
- Fixed all of the Relations to avoid superfluous Row <> InternalRow conversions
Desc: Add a hive sync config(hoodie.datasource.hive_sync.sync_comment). This config defaults to false.
While syncing data source to hudi, add column comments to source avro schema, and the sync_comment is true, syncing column comments to the hive table.
Rework of #4761
This diff introduces following changes:
- Write stats are converted to metadata index records during the commit. Making them use the HoodieData type so that the record generation scales up with needs.
- Metadata index init support for bloom filter and column stats partitions.
- When building the BloomFilter from the index records, using the type param stored in the payload instead of hardcoded type.
- Delta writes can change column ranges and the column stats index need to be properly updated with new ranges to be consistent with the table dataset. This fix add column stats index update support for the delta writes.

- This change makes sure MT records are updated appropriately on HDFS: previously after Log File append operations MT records were updated w/ just the size of the deltas being appended to the original files, which have been found to be the cause of issues in case of Rollbacks that were instead updating MT with records bearing the full file-size.
- To make sure that we hedge against similar issues going f/w, this PR alleviates this discrepancy and streamlines the flow of MT table always ingesting records bearing full file-sizes.
