If I am creating a node client total number of sockets used is 18 and if I create a transport client the number of sockets where 9. Is there any way to reduce the number of sockets for the transport client. Why do I need this many sockets? -- ---

The number of connections per node is controlled by 3 settings that specify the number of connections for each connection type (low, med and high) _transport.netty.connections\_per\_node.low_ - connections for batch oriented APIs (like recovery or batch) with high payload that will cause regular requests (like search or single index) to take longer \*transport.\*_netty.connections\_per\_node.med_ - connections for for the typical search / single doc index \*transport.\*_netty.connections\_per\_node.high_ - connections for for ping type requests (like fault detection) The default settings are low = 2, med = 6 and high = 1 If the number of connections for a given type is set to 0, requests of this type will use connections of a different type. So, you can, theoretically, go as low as 0/0/1, but it will, most likely, affect performance.
