Y Ethan Guo updated HUDI-8654:
------------------------------
Description: When there is a pending compaction, the new base files to be
generated by compaction is not available during this transaction. Given the log
files in MOR from this transaction can be attached to the base file generated
by the compaction in the latest file slice, the accurate record positions may
not be derived. However, the log files written in later delta commits after
completed compaction have accurate positions. We need to make sure that the
file group reader with position-based merging generate the correct results in
such mix of log blocks.
> Support correct merging results with record positions in log blocks generated
> during pending compaction
