Subject [jira] [Commented] (SOLR-2765) Shard/Node states

Mark Miller commented on SOLR-2765:
-----------------------------------

hmmm...you know forever I have been trying to avoid juggling potentially 100's to 1000's of
watchers per node like that. Perhaps it really is the lesser of all evils though? This whole
situation is why I initially avoided incremental update and it only went in recently. How
many zk nodes do you tend to see in that project with lots of watchers?

The problem with live nodes is that its per solr instance, and some of this info will probably
want to be per core? if we made a new structure that put cores/shards under a solr instance
node, I guess that could reduce the number watches needed - but I wonder if it's worth the
effort - I'd almost rather see the full watcher option on the current node structure fall
down first...
