Shawn Heisey commented on SOLR-1919:
------------------------------------

>From the work I've done in creating LFUCache, I know a little bit about how cache warming works, and I have no idea how to implement this.  It might be really easy, but if something doesn't happen soon I'll go ahead and close the issue.

This is part of an effort to close old issues that I have reported.  Search tag: elyograg2013springclean

> It would be useful to me if I could have Solr automatically cut off autowarming after a certain amount of time has passed, instead of configuring a percentage or an explicit count.  This would allow for maximizing performance in an environment that has scheduled maintenance scripts that do regular updates.  If your update script runs every two minutes, you could ensure that all warming is done within 60 seconds.
> I don't know whether the caches are currently warmed serially or in parallel, but warming them in parallel would allow the alternate or additional option of a "global" autowarm timeout.
