-----------------------------
Summary: Repeatedly checking configuration in
TextRecordWriter/Reader hurts performance
Key: HIVE-13789
URL: https://issues.apache.org/jira/browse/HIVE-13789
Project: Hive
Issue Type: Improvement
Reporter: Rui Li
Assignee: Rui Li
Priority: Minor
We check configuration to decide whether to escape certain characters each time
write/read a record for custom scripts.
In our benchmark this becomes a hot spot method. And fixing it improves the
execution of the custom script by 7% (3TB TPCx-BB dataset).
