Hi., to All.
We have a indice with total size of 80G(28m documents),(5 shards ,2 replicas), and when do some queries ,commonly costs 40ms,
but after we changed sharding number to 20, time costs decreased to 10~15ms
if there is any disadvantages of having 20 shards for one index?
our data node number is 5
current shard per node is about 150,but other shard is not so big
Thanks to you all.
