Subject [jira] [Commented] (SOLR-3488) Create a Collections API for SolrCloud
Date Thu, 12 Jul 2012 15:53:34 GMT


Mark Miller commented on SOLR-3488:

bq. Is it intended for a collection RELOAD action to reload all collection cores immediately?

Yes, at least initially. Essentially a convenience method for reloading your cores to pick
up changed config or settings. There may be other ways we allow that to happen more automatically
eventually, but at a minimum we need the ability to trigger a collection wide reload. There
are things to consider for a truly massive cluster - do you really want every node trying
to read the new configs form zk at the same time? That's in the future if I end up working
on it. We'd have to see how many servers it takes before you end up with a problem, if it
is indeed a problem at all.

bq. That implies downtime i assume?

I'm not sure why? Core reloads don't involve any down time.
