Subject [jira] [Commented] (HBASE-9049) Generalize ServerCallable creation to support custom callables
Date Thu, 24 Sep 2015 11:51:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14906245#comment-14906245

Jesse Yates commented on HBASE-9049:

Yeah, I'm on vacation for a little bit, but can do it when I get back (next week?). I thought
DelegatingRetryingCallable would be pretty self explanatory, but if it isn't used, that's
an issue.

> Currently, sever callables are instantiated via direct calls. Instead, we can use a single
factory and that allows more specialized callable implementations, for instance, using a circuit-breaker
pattern (or the Hystrix implementation!) to minimize attempts to contact the server.
