Hello!

Currently ElasticSearch doesn't support shard splitting. You can overshard - creating more shards during index creation, but you can't split shards.

Hey,

elasticsearch does not allow to split shards at the moment. Maybe however
aliases and overallocation can help you to work around. Instead of waiting
until a shard grows beyond a manageable size for one node (which is the
reason you want to split it) you should define more shards than expected
for your index (this is one of the reasons there are 5 shards by default
per index). In addition if your index grows beyond that maximum shard size,
you can create another index and use an alias to group them together. Why
is this similar? Because it is the same if you query 10 indices with one
shard each or or two indices with 5 five shards.

Hope this helps.

Thanks your reply. It may be a good way for that.
