             Summary: BufferedMutator should be able to flush after buffering a certain number of mutations
                 Key: HBASE-29148
                 URL: https://issues.apache.org/jira/browse/HBASE-29148
             Project: HBase
          Issue Type: Improvement
          Components: Client
            Reporter: Charles Connell
            Assignee: Charles Connell


At my company I've been experimenting with enabling {{hbase.rpc.rows.size.threshold.reject}} on our RegionServers as a protective measure, to prevent Java OOMs caused by large Multi requests. This has caused issues for some clients using BufferedMutators, which send large batches of mutations, sometimes all to a single RegionServer. It the BufferedMutator had a way to flush before hitting the RegionServer's {{hbase.rpc.rows.warning.threshold}}, then it could gets its mutations done successfully. This is easy to add.
