-------------------------------------
Summary: Limit batch size for Flat Parquet Reader
Key: DRILL-6147
URL: https://issues.apache.org/jira/browse/DRILL-6147
Project: Apache Drill
Issue Type: Improvement
Components: Storage - Parquet
Reporter: salim achouche
Assignee: salim achouche
Fix For: 1.13.0
The Parquet reader currently uses a hard-coded batch size limit (32k rows) when
creating scan batches; there is no parameter nor any logic for controlling the
amount of memory used. This enhancement will allow Drill to take an extra input
parameter to control direct memory usage.
