Hi everyone, my everyday documents is about 20 million records and one index per day.
I know the default setting is 5 shards 1 replica per index.
should I change the setting such as 3 shards and 2 replica, and does the setting performance be better or not?
How can I tune the shards and replica to improve my ES system performance and maintain the durability?
btw, I set 4 nodes in a cluster.
thank you in advance!
