Ivan Sadikov updated SPARK-41248:

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 Apache Spark JSON 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.
