[GitHub] [druid] jon-wei opened a new pull request #11024: Add resources used to EXPLAIN PLAN FOR output
jon-wei opened a new pull request #11024:
URL: https://github.com/apache/druid/pull/11024
This PR adds an additional `RESOURCES` field to the output of `EXPLAIN PLAN FOR ` queries, which contains a JSON-serialized Set of the Resources that were used by the query (for example, the datasources or views that the query accessed).
This is useful for callers that wish to know the datasources or views that would be accessed by a query but don't want to deal with the complexity of parsing either the query or the explain plan.
This PR has:
- [x] been self-reviewed.
- [ ] added documentation for new or modified features or behaviors.
- [ ] added Javadocs for most classes and all non-trivial methods. Linked related entities via Javadoc links.
- [ ] added or updated version, license, or notice information in [licenses.yaml](https://github.com/apache/druid/blob/master/dev/license.md)
- [x] added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader.
- [x] added unit tests or modified existing tests to cover new code paths, ensuring the threshold for [code coverage](https://github.com/apache/druid/blob/master/dev/code-review/code-coverage.md) is met.
- [ ] added integration tests.
- [ ] been tested in a test Druid cluster.
