Hi Max,

Are you referring to the coordinator dynamic configuration ? Dynamic configuration helps you to change certain behaviour on the fly without having to restart the server. Look at dynamic-configuration.

If I want to remove or recover specific segment in datasource.

There is plenty of documentation around deleting/dropping data. Check,

  1. http://druid.io/docs/latest/tutorials/tutorial-delete-data.html

  2. http://druid.io/docs/latest/operations/rule-configuration.html

  3. http://druid.io/docs/latest/ingestion/delete-data.html

As long as the segments dropped from Druid are available in the deep storage, they can be loaded back to Druid. See Reloading Dropped Data section from http://druid.io/docs/latest/operations/rule-configuration.html.
