I am using Elastic-search version 7.5.2 .
My cluster has 1 master node and 3 data nodes and 1 co-ordinating node which is essentially a kibana node.
The workflow is beats->logstash->elasti-search->kibana.
All my logs are dumping to Elastic-search nodes from the logstash after filtering. I would like to know how my master node is load balancing the logs data across my 3 nodes and what if i need to send some logs to go to only 2 nodes and other data to go to last node. how can i achieve it.
