-------------------------------------
Summary: Investigate Hudi vs Raw Parquet table discrepancy
Key: HUDI-3891
URL: https://issues.apache.org/jira/browse/HUDI-3891
Project: Apache Hudi
Issue Type: Bug
Reporter: Alexey Kudinkin
Assignee: Alexey Kudinkin
While benchmarking querying raw Parquet tables against Hudi tables, i've run
the test against the same (Hudi) table:
# In one query path i'm reading it as just a raw Parquet table
# In another, i'm reading it as Hudi RO (read_optimized) table
Surprisingly enough, those 2 diverge in the # of files being read:
_Raw Parquet_
