Subject [jira] [Comment Edited] (DRILL-3242) Enhance RPC layer to offload all request work onto a separate thread.
Date Thu, 22 Oct 2015 04:21:27 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957116#comment-14957116

------------------------------------------------------------------

I think this patch is important for high concurrency. We should not keep a RPC thread too
busy. Can you rebase on master? (And open a pull request for more comments, since most developers
aren't looking at RB anymore?)

> Right now, the app is responsible for ensuring that very small amounts of work are done
on the RPC thread.  In some cases, the app doesn't do this correctly.  Additionally, in high
load situations these small amounts of work become no trivial.  As such, we need to make RPC
layer protect itself from slow requests/responses.
