Subject [jira] [Commented] (CASSANDRA-4414) Ship the exact cause for timeout and unavailable exception back to the client
Date Wed, 11 Jul 2012 23:01:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13412278#comment-13412278

Jonathan Ellis commented on CASSANDRA-4414:
-------------------------------------------

bq. I do think we should break this apart into a separate exception

I still would like to do this in an ideal world but I think our hands might be tied by the
client community...  unless we're willing to break everyone who doesn't add IPE, the optional
field is a better approach.

> Currently when a client gets a timeout exception, it doesn't know what happened. But
sever side we usually know a little more than that. For example, for 99% of the timeouts at
CL > ONE, we will have some replica that have acknowlege. I think it could be useful to
send that information to the client with the exception. That could help with monitoring, "post-mortem"
analysis and debugging.
> Unavailable exceptions could also ship which nodes were alive and which ones where not.
