[HUDI-3378] RFC-46 rebase by wzx140 · Pull Request #7345 · apache/hudi

Change Logs

Modify composeSchemaEvolutionTransformer to get the evolved schema
Support schema evolution for parquet
Clear cache in HoodieInMemoryHashIndex after each test in sql test
Add prefixFieldName to multi record keys in RowKeyGenerator
Sometimes, we need to extract the recordKey from the partition-dropped data. Change RowKeyGenerator's behaviors to be consistent with avro key generator.
Fix kyro register. "AbstractMethodError". I found that relocation shade of kryo changes the method signature. We should not let Spark call HoodieSparkKryoRegistrar's method related to kryo.

RFC46 Phase 1
To achieve stated goals of avoiding unnecessary conversions into intermediate representation (Avro), we promote HoodieRecord to become a standardized API of interacting with a single record holding internal engine-specific representation of the payload and replace all accesses from HoodieRecordPayload. We extract Record Combining (Merge) API from HoodieRecordPayload into a standalone, stateless component (engine). More information can be found in RFC46.

HoodieAvroRecordMerger and HoodiePayload are used together to support all existing features. Now the spark part has been realized. The following is the caveats with HoodieSparkRecordMerger

Only Parquet log is now supported
For sql merge api, it will automatically backoff to HoodieAvroRecordMerger
Not support hoodie.metadata.index.column.stats
SparkMerger should use "HoodieSparkValidateDuplicateKeyRecordMerger" with "hoodie.sql.insert.mode=strict"

Impact

Rebase release-feature-rfc46 on master

Documentation Update

Describe any necessary documentation update if there is any new feature, config, or user-facing change

The config description must be updated if new configs are added or the default value of the configs are changed
Any new feature or user-facing change requires updating the Hudi website. Please create a Jira ticket, attach the

Great job @wzx140!

[minor] add more test for rfc46 (apache#7003) ## Change Logs - Add HoodieSparkValidateDuplicateKeyRecordMerger behaving the same as ValidateDuplicateKeyPayload. We should use it with config "hoodie.sql.insert.mode=strict". - Fix nest field exist in HoodieCatalystExpressionUtils - Fix rewrite in HoodieInternalRowUtiles to support type promoted as avro - Fallback to avro when use "merge into" sql - Fix some schema handling issue - Support delta streamer - Convert parquet schema to spark schema and then avro schema(in org.apache.hudi.io.storage.HoodieSparkParquetReader#getSchema). Some types in avro are not compatible with parquet. For ex, decimal as int32/int64 in parquet will convert to int/long in avro. Because avro do not has decimal as int/long . We will lose the logic type info if we directly convert it to avro schema. - Support schema evolution in parquet block [Minor] fix multi deser avro payload (apache#7021) In HoodieAvroRecord, we will call isDelete, shouldIgnore before we write it to the file. Each method will deserialize HoodiePayload. So we add deserialization method in HoodieRecord and call this method once before calling isDelete or shouldIgnore.

This PR introduces so many regressions, don't think it is a valuable PR from the gains. Let's be more conservertive to accept huge PRs and more rigorous for code reviewing without sufficient tests.

…ider javadoc names its real caller - HoodieSparkValidateDuplicateKeyRecordMerger: from its introduction in apache#7345 the merger appeared in production sources only as a TODO in ProvidesHoodieConfig, beside the ValidateDuplicateKeyPayload selection that apache#12588 deleted, so the class doc and the test comment now say it was never wired in-repo rather than unwired since apache#12588. - org.apache.hudi.cli.SchemaProvider: the class javadoc claimed Hudi Streamer as its user; it now names the CLI bootstrap path (BootstrapExecutorUtils loading the configured implementation by class name) and points to org.apache.hudi.utilities.schema for the Streamer provider.

…9164) One suite per class, each in the package of the class it covers: - TestCachingIterator (hudi-spark-common, org.apache.hudi.util): full iteration and hasNext idempotency against a counting source iterator. The trait has had no in-repo user since #17457 moved the datasource read paths onto the file-group reader; removing it is left to a separate cleanup. - TestHoodieCatalog: HoodieCatalog.convertTransforms for identity columns, a single bucket transform, a sorted bucket transform keeping its sort columns, and the two rejections (multiple bucket transforms, unsupported transform). HoodieSparkCatalogUtils.MatchBucketTransform is covered through it, including the sorted_bucket arm. - TestBasicStagedTable (added by #19251): commit leaves the catalog alone, abort drops the staged table through it. - TestHoodieSparkValidateDuplicateKeyRecordMerger: the strategy id pinned as the literal, since a table that loads the merger through hoodie.write.record.merge.custom.implementation.classes selects it by that id and persists it, plus the pre-combining fallback to DefaultSparkRecordMerger. The merger was never wired in-repo: from #7345 it appeared in production sources only as a TODO in ProvidesHoodieConfig, beside the ValidateDuplicateKeyPayload selection that #12588 deleted; the class doc now says so instead of pointing at that deleted payload. - TestProcedureParameterImpl (added by #19161): the factories' required/default semantics, toString field presence, a hashCode inequality case, and an equals case that isolates required from default. - TestCliSchemaProvider: the CLI bootstrap SchemaProvider in org.apache.hudi.cli (distinct from the Streamer one; named to avoid the TestSchemaProvider stubs in hudi-utilities and hudi-kafka-connect), shaped like flink's TestSchemaProviderCompatibility: legacy provider, modern provider whose target falls back to the overridden source HoodieSchema, and null handling. The getTargetHoodieSchema catch comment now names the two provider shapes that reach it. Production changes are limited to those two comments; no behavior change. --------- Co-authored-by: voon <voonhousu@gmail.com>
