Subject [jira] [Commented] (SOLR-5477) Async execution of OverseerCollectionProcessor tasks
Date Mon, 16 Dec 2013 18:51:07 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13849581#comment-13849581

Mark Miller commented on SOLR-5477:
-----------------------------------

On a related note, I think our current timeouts are much too low at one minute. If nothing
comes up to make us think the call is still not in progress, we should be willing to wait
much longer I think.

> Typical collection admin commands are long running and it is very common to have the
requests get timed out.  It is more of a problem if the cluster is very large.Add an option
to run these commands asynchronously
> add an extra param async=true for all collection commands
> the task is written to ZK and the caller is returned a task id. 
> as separate collection admin command will be added to poll the status of the task
> command=status&id=7657668909
> if id is not passed all running async tasks should be listed
> A separate queue is created to store in-process tasks . After the tasks are completed
the queue entry is removed. OverSeerColectionProcessor will perform these tasks in multiple
threads
