[GitHub] [druid] yuanlihan opened a new issue #9801: Enable transformation in compaction task
yuanlihan opened a new issue #9801:
URL: https://github.com/apache/druid/issues/9801
### Motivation
Currently, we can customize `dimensionsSpec` and `metricsSpec` during compaction task. It would be convenient to enable `transformSpec` during `compact` task when compacting/re-indexing the existing datasource. And we can also introduce `dimensionsSpec`, `metricsSpec` and `transformSpec` to `DataSourceCompactionConfig`.
Note that we can also reindex existing datasource through `index` task with [`DruidInputSource`](https://druid.apache.org/docs/latest/ingestion/native-batch.html#druid-input-source), but we can reuse the scheduling mechanism of auto compaction with `compact` task.
