> 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.
> Benchmark results are attached below.
