jon-wei opened a new pull request #9971: URL: https://github.com/apache/druid/pull/9971
This PR implements the follow areas of proposal https://github.com/apache/druid/issues/9953: - Modifying BroadcastDistributionRule - Assigning and balancing segments - Segment loading in brokers, realtime tasks, and indexers Key changes: - Adjusts BroadcastDistributionRule to remove the colocated datasources concept - Adjusts the segment balancers to skip balancing for segments that were assigned via broadcast rule - CliBroker, CliPeon, CliIndexer now bind ZKCoordinator and related classes for loading segments - Updates DruidCluster, DruidServer, ServerType and related to support the concept of a "broadcast target", separate from a "replication target" - SegmentChangeRequestLoad is updated to never prune the load spec when deserializing a DataSegment. This is needed for Brokers to load segments - A new flag has been added to the peon, indicating whether it will be running a queryable task. Non-queryable tasks such as batch tasks will not load segments.
