Subject [jira] [Commented] (DRILL-1197) C++ Client. Differentiate socket/handshake/query timeout for deadline timer.
Date Tue, 29 Jul 2014 21:21:41 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14078383#comment-14078383

Xiao Meng commented on DRILL-1197:
----------------------------------

Hi Parth,

I agree. It is better to separate a JIRA [#DRILL-1219].  I cannot reproduce the problem (handleHandleshakeTimeout
trigger HandleRead and signal errors) at the moment and previously the application seems confused
and cannot identify the right error type.

Also, after shutdown, is the client's connection still usable? I don't
think it is. If it is not, then we have a much bigger problem. We cannot
allow a client connection to die because the server took too long to
respond!

If we use shutdown_both, the socket is not usable anymore. In our application, we will open
a new connection to re-sumbit the query, so it is not a problem. If I understand it correctly,
you assume that we should reuse the socket connection after timed out?

> [#DRILL-852] introduced deadline timer to C++ Client. It use a global setting of timeout
for all reading operation. We should differentiate timeout for different operations and also
populate the status to client library user.
