Hello? I'm newbie to Elasticsearch.
Consider there are 1 master nodes and 6 data nodes(A,B,C,D,E,F).
I'd like to put 'log\_a' index's shard and replica to first three nodes(A,B,C).
I'd like to put 'lob\_b' index's shard and replica to other nodes(D,E,F).
Is this scenario possible?
If it is, then how can I implement it?
I just want to allocate specific index's shard(primary and replica) and replica to specific set of nodes.

You can use [allocation filtering](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/shard-allocation-filtering.html) to do this. However it won't distinguish between primary and replica.
