Mark Miller commented on SOLR-3488:
-----------------------------------

I'll post an initial patch just for create soon. It's just a start though. I've added a bunch of comments for TODOs or things to consider for the future. I'd like to start simple just to get 'something' in though.

So initially, you can create a new collection and pass an existing collection name to determine which shards it's created on. Would also be nice to be able to explicitly pass the shard urls to use, as well as simply offer X shards, Y replicas. In that case, perhaps the leader could handle ensuring that. You might also want to be able to simply say, create it on all known shards.

Further things to look at:

* other commands, like remove/delete.
* what to do when some create calls fail? should we instead add a create node to a queue in zookeeper? Make the overseer responsible for checking for any jobs there, completing them (if needed) and then removing the job from the queue? Other ideas.
