> 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
