[jira] [Updated] (SPARK-41248) Add config flag to control before of JSON partial results parsing in SPARK-40646
[ https://issues.apache.org/jira/browse/SPARK-41248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ivan Sadikov updated SPARK-41248:
---------------------------------
Description:
This is a follow-up for https://issues.apache.org/jira/browse/SPARK-40646.
It was observed in internal benchmarks that the JSON partial results parsing can be 30% slower compared to parsing without the patch. I could not find a regression and the OSS benchmark results are very similar with and without SPARK-40646.
However, I would still like to add a config flag to enable/disable the feature in the case the regression is observed in users' queries.
