clintropolis opened a new pull request #10460: URL: https://github.com/apache/druid/pull/10460
### Description This PR fixes an issue caused by #9638 being a bit over-ambitious and wiring up calcite arrays to druid array types, which resulted in array types leaking into the rest of the query engine. It also fixes an bug where expressions with explicitly array typed output could incorrectly set `ExpressionPlan.Trait.SINGLE_INPUT_MAPPABLE` resulting in an incorrect dimension selector being used. <hr> This PR has: - [x] been self-reviewed. - [x] added Javadocs for most classes and all non-trivial methods. Linked related entities via Javadoc links. - [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. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
