> Use a disk-based store to save more information in live UI to help debug
> ------------------------------------------------------------------------
>
> Key: SPARK-38550
> URL: https://issues.apache.org/jira/browse/SPARK-38550
> Project: Spark
> Issue Type: Task
> Components: Spark Core, SQL
> Affects Versions: 3.3.0
> Reporter: Linhong Liu
> Assignee: Linhong Liu
> Priority: Major
> Fix For: 3.4.0
>
>
> In Spark, the UI lacks troubleshooting abilities. For example:
> * AQE plan changes are not available
> * plan description of a large plan is truncated
> This is because the live UI depends on an in-memory KV store. We should
> always be worried
> about the stability issues when adding more information to the store.
> Therefore, it's better to add a disk-based store to save more information
