Shard splitting and dynamic cluster expansion?

Elastic Stack Elasticsearch
1

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 :frowning:

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.
