kgyrtkirk opened a new pull request, #17985:
URL: https://github.com/apache/druid/pull/17985
* `QueryHandler` switches to a new communication api when
`plannerStrategy=DECOUPLED` in case the `QueryMaker` implements
`QueryMaker.FromDruidLogical`
* adds a `prePlanned` context variable which switches on a delegate for
`DartQueryMaker`; in this mode the `QueryDefintion` is planned up-front
* depending on `plannerStrategy`:
* `COUPLED`: (default) utilizes `QueryKitBasedMSQPlanner` to obtain the
`QueryDefintion` and submits that
* `DECOUPLED`: translates directly the `DruidLogicalNode` into
`QueryDefinition` via `QueryDefintionTranslator`
* some refactors in `DartQueryMaker` and in `MSQTaskQueryMaker` to be able
to share as much as possible with the existing execution modes
note: if testing from Druid console: the `limit inline results` should be
disabled for now to get results.
