[jira] [Created] (SPARK-38550) Use a disk-based store to save more information in live UI to help debug

Linhong Liu created SPARK-38550:
-----------------------------------

             Summary: 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


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
