> ReplicationManager: Introduce basic limits on ReplicateContainer commands
> -------------------------------------------------------------------------
>
> Key: HDDS-8110
> URL: https://issues.apache.org/jira/browse/HDDS-8110
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
>
> Create a configuration on Replication Manager that sets the limit of inflight
> replicate container commands to 20. The intention is to revisit this limit
> later to make it more dynamic, but this is a starting point.
> Then create a method on ReplicationManager
> createThrottledReplicateContainerCommand, which create the
> replicateContainerCommands and take into consideration the pending commands
> on the target datanode. If not targets for the command have capacity, it will
> throw an exception.
> Adjust the various places in ReplicationManager which send the
> replicateContainer commands to use the new method.
> Additionally switch the default replication mode to Push (rather than
> download) and ensure the LegacyReplicationManager continues to use download
> as before.
