Subject [jira] [Commented] (HBASE-10355) Failover RPC's from client using region replicas
Date Wed, 19 Feb 2014 19:02:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13905878#comment-13905878

Nicolas Liochon commented on HBASE-10355:

bq. We should fix either that or this
I think we need micro seconds, at least for testing: a synchronous get takes ~0.2ms on my
1Gb network, so if we want to play with the secondary calls probability with probability different
than 0 & 100%, we need it. As well, for end user, it makes send to use values like 50m
microseconds: compared to 1ms, it divides the latency by 2. And the perf will be much better
on a modern hardware actually.

bq. It works with HBASE-10472, right?
Yes, plus HBASE-10525

bq. I guess CompletionService is also available for jdk6
Actually yes. I was wrong. But the v2 simplifies a little the code compared to the default
CompletionService, so I prefer to keep it actually.
