[HUDI-6200] Enhancements to the MDT for improving performance of larger indexes. (#8684)
Major changes
Moved MDT compaction out of the pre-commit phase into the initialization phase within write client
MDT compaction and clean is attempted during WriteClient initialization stage before any changes to the dataset are initiated.
This ensures correct ordering of the compactions
This also creates a codepath to call compaction on the MDT without actual commits
Removed support for setting fileGroup count to the MetadataPartitionType enum
Since enums are singletons, this design prevented having multiple different datasets with different fileGroup count for MDT parttitions in the same JVM instance
When there are large number of fileGroups (assume 10K+) for a MDT partition, listing fileSlices for it may take a considerable amount of time (10K slices * M basefile version + 10K * N log files per slice). Hence, this should not be done as part of the HoodieBackedTableMetadataWriter constructor and delayed to whenever actually required (prepRecords).
When initializing multiple MDT partitions together, they are handled one at a time
Reduces memory requirements as larger indexes may need a huge amount of memory
Improves chances of indexes being built.
If the FILES partition is already initialized, it is listed to find the files thereby saving expensive entire dataset listing while
initializing addtional partitions
Initial commit into MDT to initialize a new partition is not a bulkCommit
HFiles are created directly for the first commit
Since first commits write a large amount of data, bulkCommit into a basefile is much faster than writing log files
Added SparkHoodieMetadataBulkInsertPartitioner as the bulk insert partitioner. It is optimized to partition records in a single pass.
The number of fileGroups for each MDT partition are determined as part of the initialization process.
This allows the fileGroup count to be optimized based on the number of records being added
Other changes:
Created helper method to find if MDT partition is enabled: HoodieTableConfig.isMetadataPartitionEnabled()
Created helper method to set state (enabled/disabled) of MDT partition: HoodieTableConfig.setMetadataPartitionState()
Created helper method to delete MDT: HoodieTableMetadataUtil.deleteMetadataTable(). It correctly updates the hoodie.properties file.
Created helper method to set inflight state (enabled/disabled) of MDT partition: HoodieTableMetadataUtil.setMetadataInflightPartitions
Created helper method to delete MDT partition: deleteMetadataTablePartition. It correctly updates the hoodie.properties file.
