ReplicationSink at the sink server usually goes through all Edits > and creates map of table -> list of rows grouped by clusterIds, and performs > batch mutation of all rows per table level. However, there is no limit to no > of Rows that are sent as part of batch mutate call. If no of rows > limit > threshold defined by hbase.rpc.rows.warning.threshold, we usually get warn > "Large batch operation detected". If hbase.rpc.rows.size.threshold.reject is > turned on, RS will reject the whole batch without processing. > We should let Replication Sink honour this threshold value and accordingly > keep the size lower per batch mutation call. > Replication triggered batch mutations should always be consumed but keeping > limit of mutation low enough will let the system function at the same pace > and without triggering redundant warnings. This will also restrict > exploitation of cpu cycles at the destination server. -- This message was sent by Atlassian Jira (v8.3.4#803005)
