Issue: Even though `CompactionTuningConfig` allows a `maxColumnsToMerge` config (to optimize memory usage, particulary for datasources with many dimensions), the corresponding client object `ClientCompactionTaskQueryTuningConfig` (used by the coordinator duty `CompactSegments` to trigger auto-compaction) does not contain this field. Thus, the value of `maxColumnsToMerge` specified in any datasource compaction config is ignored. Changes: - Add field `maxColumnsToMerge` in `ClientCompactionTaskQueryTuningConfig` and `UserCompactionTaskQueryTuningConfig` - Fix tests |
