Apache Druid

You can do something like this: <https://druid.apache.org/docs/latest/data-management/automatic-compaction.html#set-frequency-of-compaction-runs>

You can also run a manual compaction for a longer time period, and it will process all time chunks within the time period one after another, only using the same amount of resources that a single auto-compaction uses (in your case it sounds like three at a time.)

<@U035FNDU6HH> If i change the `druid.coordinator.compaction.period` in the `coordinator/runtime.properties` file, do I need to restart the cluster?

you’ll also need
```druid.coordinator.dutyGroups=["compaction"]
druid.coordinator.compaction.duties=["compactSegments"]```
in order for `druid.coordinator.compaction.period` to take effect.
