### Is your feature request related to a problem or challenge? It would be useful to collect plans from queries automatically, without needing to explicitly add `EXPLAIN ANALYZE`. This would ensure that the original application would not need to change, as the queries would still return data as normal, while the plans would be printed to `stdout`/`stderr`. Some existing systems already support this feature, like [`auto_explain`](https://www.postgresql.org/docs/18/auto-explain.html) in Postgres and [`eqp`](https://www.sqlite.org/eqp.html) in SQLite. ### Describe the solution you'd like Some `datafusion.execution.auto_explain` config that would enable this feature. I already created a small proof of concept and this feature would be relatively easy to implement. We just need to wrap execution plans in an `AnalyzeExec`. This `AnalyzeExec` would also need a flag to know when it's in the `auto_explain` mode, in which case it would print the plans and return the input batches. I would be happy to create a PR with this. ### Describe alternatives you've considered Adding `EXPLAIN ANALYZE` manually, but this changes the application. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
