Jean-Daniel Cryans commented on HBASE-7325: ------------------------------------------- [~gabriel.reid] alright +1 [~lhofhansl], I'm going to commit this to trunk but I was wondering if you'd want this in 0.94? > Replication reacts slowly on a lightly-loaded cluster > ----------------------------------------------------- > > Key: HBASE-7325 > URL: https://issues.apache.org/jira/browse/HBASE-7325 > Project: HBase > Issue Type: Bug > Components: Replication > Reporter: Gabriel Reid > Priority: Minor > Attachments: HBASE-7325.patch > > > ReplicationSource uses a backing-off algorithm to sleep for an increasing > duration when an error is encountered in the replication run loop. However, > this backing-off is also performed when there is nothing found to replicate > in the HLog. > Assuming default settings (1 second base retry sleep time, and maximum > multiplier of 10), this means that replication takes up to 10 seconds to > occur when there is a break of about 55 seconds without anything being > written. As there is no error condition, and there is apparently no > substantial load on the regionserver in this situation, it would probably > make more sense to not back off in non-error situations. -- This message is automatically generated by JIRA.
