Hi, We are planning to create Index with 2 replica's and in order to have better performance we are thinking of doing the replication Async. I'm creating the Index this way - curl -XPUT '[http://localhost:9200/xyz/](http://localhost:9200/xyz/)' -d '{ "settings" : { "number\_of\_shards" : 2, "number\_of\_replicas" : 2, "replication" : "async" } }' Is the above correct? How do i confirm that my replication is Async, is there any curl command for confirmation. Thanks Pranav. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
