I'm unclear if ES supports this... I don't want to be limited to the size of my cluster. It looks like SOLR supports this. IE split a shard, then replicate it to a new server. Does ES support this yet... this is going to be the key decision maker for me. If I can't add more servers to scale my load then it's kind of a show stopper I'm afraid ☹ -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You can easily add more nodes. You cannot however add more shards to an index, which is probably what you are getting at. The simple solution to that is to over allocate your initial shard count to cater for more servers.

The way to go is by using index aliases. If you need more shards at some point, create a new index with as many shards you need and add it to the alias.
