Alexey Kudinkin updated HUDI-4911:
----------------------------------
Description:
Currently {{HoodieMetadataMergedLogRecordReader }}will flush internal record
cache before each lookup which makes every lookup essentially do re-processing
of the whole log-blocks stack again.
We should avoid that and only do the re-parsing incrementally (for the keys
that ain't already cached)
