@ -965,7 +965,7 @@ You can configure automatic compaction through the following properties:
|--------|-----------|--------|
|`dataSource`|dataSource name to be compacted.|yes|
|`taskPriority`|[Priority](../ingestion/tasks.md#priority) of compaction task.|no (default = 25)|
|`inputSegmentSizeBytes`|Maximum number of total segment bytes processed per compaction task. Since a time chunk must be processed in its entirety, if the segments for a particular time chunk have a total size in bytes greater than this parameter, compaction will not run for that time chunk. Because each compaction task runs with a single thread, setting this value too far above 1–2GB will result in compaction tasks taking an excessive amount of time.|no (default = Long.MAX_VALUE)|

|`maxRowsPerSegment`|Max number of rows per segment after compaction.|no|
|`skipOffsetFromLatest`|The offset for searching segments to be compacted in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) duration format. Strongly recommended to set for realtime dataSources.
