We would like to know how many tcp connection will the default rest client will open ? We are planning to move es5.6.11 from es2.3.2. We are seeing indexing performance degradation. So far we used node client for indexing in es2.3.2. Incase of node client with mesh topology the client have dedicated 3 channels ( here i would like to know how many respective tcp connections) with each data node. But in Rest client default maxTotalConnection is 30 and perRoute value is 10 - Here only pool of only 30 connections for the cluster.
What this 30 actually means ? Is it 30 socket connections. Incase if my cluster has more then 30 nodes whether it will be bottleneck ?
