Can you provide the full output of the cluster stats API?

It's too large,so I divide it into two segments


(Christian Dahlqvist) #7

Given the data volume and size of the cluster, I believe you have far too many shards. Having a lot of small shards can be very inefficient. See this blog post for some further guidance on sharding practices.
