superivaj opened a new issue, #12550: URL: https://github.com/apache/druid/issues/12550
### Affected Version The setting `maxColumnsToMerge` was introduced in version 0.21.0 but the problem was identified on version 0.22.1. ### Description Configuring a DataSource with an automatic compaction that includes `maxColumnsToMerge` will make the automatic compaction to ignore this field. This field is important to reduce and optimize memory usage, particularly for data sources with many dimensions. The bug has been identified on the following classes: - server/src/main/java/org/apache/druid/client/indexing/ClientCompactionTaskQueryTuningConfig.java - server/src/main/java/org/apache/druid/server/coordinator/UserCompactionTaskQueryTuningConfig.java Both of these classes are missing the `maxColumnsToMerge` property. A fix was implemented to add the missing property to these two classes in our environment (fork). The fix was tested succesfully. -- This is an automated message from the Apache Git Service.
