public javax.ws.rs.core.Response getDataSource(String dataSourceName,
                                               String full)

markAsUsedAllNonOvershadowedSegments

public javax.ws.rs.core.Response markAsUsedAllNonOvershadowedSegments(String dataSourceName)

markAsUsedNonOvershadowedSegments

public javax.ws.rs.core.Response markAsUsedNonOvershadowedSegments(String dataSourceName,
                                                                   DataSourcesResource.MarkDataSourceSegmentsPayload payload)

markSegmentsAsUnused

public javax.ws.rs.core.Response markSegmentsAsUnused(String dataSourceName,
                                                      DataSourcesResource.MarkDataSourceSegmentsPayload payload)

markAsUnusedAllSegmentsOrKillUnusedSegmentsInInterval

@Deprecated
public javax.ws.rs.core.Response markAsUnusedAllSegmentsOrKillUnusedSegmentsInInterval(String dataSourceName,
                                                                                                   String kill,

Deprecated.

When this method is removed, a new method needs to be introduced corresponding to the end point "DELETE /druid/coordinator/v1/datasources/{dataSourceName}" (with no query parameters). Ultimately we want to have no method with kill parameter - DELETE `{dataSourceName}` to mark all segments belonging to a data source as unused, and DELETE `{dataSourceName}/intervals/{interval}` to kill unused segments within an interval

Provides serverView for a datasource and Interval which gives details about servers hosting segments for an interval. Used by the realtime tasks to fetch a view of the interval they are interested in.

isHandOffComplete

public javax.ws.rs.core.Response isHandOffComplete(String dataSourceName,

Used by the realtime tasks to learn whether a segment is handed off or not. It returns true when the segment will never be handed off or is already handed off. Otherwise, it returns false.
