Is there a Connect Pool Limit in either the Elastic Search Server or Java Client.
If we have 1 Node, how many concurrent connections or calls can be made to this node.
If we have N Nodes, how many concurrent connections or calls can be made to all nodes.
How do we increase this limit?
Basically what we are noticing is after request rate / second 25 K - 30 K we are not able to increase this per node.
The search rate is 3500/ Second max for 7 node cluster
The other is the loads are going only to a couple of the nodes of the 7 and the rest of the nodes are idle. There are 5 Shards per index only 1 shard is present in the node, why is it going only to these 2 nodes.
