Feng Honghua created HBASE-9501: ----------------------------------- Summary: No throttling for replication Key: HBASE-9501 URL: https://issues.apache.org/jira/browse/HBASE-9501 Project: HBase Issue Type: Improvement Components: Replication Reporter: Feng Honghua
When we disable a peer for a time of period, and then enable it, the ReplicationSource in master cluster will push the accumulated hlog entries during the disabled interval to the re-enabled peer cluster at full speed. If the bandwidth of the two clusters is shared by different applications, the push at full speed for replication can use all the bandwidth and severely influence other applications. Though there are two config replication.source.size.capacity and replication.source.nb.capacity to tweak the batch size each time a push delivers, but if decrease these two configs, the number of pushes increase, and all these pushes proceed continuously without pause. And no obvious help for the bandwidth throttling. >From bandwidth-sharing and push-speed perspective, it's more reasonable to >provide a bandwidth up limit for each peer push channel, and within that >limit, peer can choose a big batch size for each push for bandwidth efficiency.
