Apache Spark reassigned SPARK-40150:
------------------------------------
Assignee: Apache Spark
> Dynamically merge File Splits
> -----------------------------
>
> Key: SPARK-40150
> URL: https://issues.apache.org/jira/browse/SPARK-40150
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Jackey Lee
> Assignee: Apache Spark
> Priority: Major
>
> We currently use maxPartitionBytes and minPartitionNum to split files and use
> openCostInBytes to merge file splits. But these are static configurations,
> and the same configuration does not work in all scenarios.
> This PR attempts to dynamically merge file splits, taking into the
> concurrency while processing more data in one task.
