-----------------------------------
Summary: Late release of compressor memory in the Parquet writer
Key: DRILL-8366
URL: https://issues.apache.org/jira/browse/DRILL-8366
Project: Apache Drill
Issue Type: Bug
Components: Storage - Parquet
Affects Versions: 1.20.2
Reporter: James Turton
Assignee: James Turton
Fix For: 1.20.3
The Parquet writer waits until the end of the entire write before releasing its
compression codec factory. The factory in turn releases compressors which
release direct memory buffers used during compression. This deferred release
leads a build up of direct memory use and can cause large write jobs to fail.
The Parquet writer can instead release the abovementioned each time that a
file/row group is flushed.
