Shard reside and Replica reside Logic In elasticsearch Cluster

Elastic Stack Elasticsearch
1

Hi Everyone,

Can anyone please explain how the shards and indices are distributed for the particular index......... Is there any logic for that?..

In most of the documents it is like elastic-search default feature of elasticsearch ......
Lets say i have an index ...Default it have 5 shards and 10replicas....We have a cluster with 4 nodes.....And in our cluster all the replicas are on same node....and 5 shards are in remaining 3 nodes..

Can anyone please explain how the shard residing and replicas take place

Thanks in advance
Balu

Having replicas on the same node does not really matter.
Why do you think it's important?
