Internally to the > HBase client those puts are batched into MultiActions. The total number of > put operations shown in the RegionServer's put metrics histogram never > increases from 0 even though millions of such operations are made. Needless > to say the latency for those operations are not measured either. The value of > HBASE-5533 metrics are suspect given the client will batch put and delete ops > like this. > I had a fix in progress but HBASE-6284 messed it up. Before, MultiAction > processing in HRegionServer would distingush between puts and deletes and > dispatch them separately. It was easy to account for the time for them. Now > both puts and deletes are submitted in batch together as mutations. -- This message is automatically generated by JIRA.
