Hello,
My Logstash creates 17 indices daily basis, and stored size is as below.
Should I reduce Shard number for small sized indices?
OR merge some of indices?
_e.g. combine "access\_xpg\_prd\_20180928", "access\_ui50\_prd\_20180928" and "access\_scs\_prd\_20180928" to "access\_prd\_20180928"_

Having lots of small shards like this [can be very inefficient](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster). All your shards are very small, so I do not see any need for more than a single primary shard for any of them. Merging indices is also an option. If you have a long retention period I would even recommend switching to monthly indices for the vast majority of them, even after they are combined.

That was what i wated to heard from you to confirm. Yes we combined some of similar indices today.
Can you please advise or share the reference page how i can combine/merge old indices in warm nodes??
Thank you!!

You will need to use the reindex API.
