Apache Spark reassigned SPARK-42686:
------------------------------------
Assignee: (was: Apache Spark)
> TaskMemoryManager debug logging is expensive
> --------------------------------------------
>
> Key: SPARK-42686
> URL: https://issues.apache.org/jira/browse/SPARK-42686
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.3.2
> Reporter: Alkis Evlogimenos
> Priority: Major
>
> TaskMemoryManager debug logging is expensive mostly because formatting
> operations are done eagerly and some of them are quite expensive (i.e.
> humanized strings). This causes visible CPU usage in scan benchmarks for
> example.
