Anshum Gupta commented on SOLR-5477:
------------------------------------
Thanks for the inputs Hoss.
Having them in zk certainly makes it easier to track completed tasks but I was
just trying to
1. Keep it simpler for now
2. Have no dependency on zk for CoreAdmin tasks.
Pt. 2 that I mentioned however takes a back seat if we don't intend to use it
for purely core admin calls from other clients.
About generating request IDs at client-side, I'll ping you on IRC and get more
clarity on that.

> 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
