Alexey Kudinkin created HUDI-4319:
-------------------------------------
Summary: Dictionary encoding not applied by Parquet when
bulk-inserting
Key: HUDI-4319
URL: https://issues.apache.org/jira/browse/HUDI-4319
Project: Apache Hudi
Issue Type: Bug
Reporter: Alexey Kudinkin
Fix For: 0.12.0
In our tests we've discovered that Hudi doesn't properly propagate
"hoodie.parquet.dictionary.enabled" config to Parquet writer when doing
bulk-insert.
This leads to PLAIN_DICTIONARY encoding not applied substantially bloating the
footprint on storage in our tests by about 30%:
