I am new to Splunk and reading about load balancing. According the Splunk documentation we can setup load balancer to distribute the search requests to search head members. Then search head will query indexer cluster to get the required data. For example My indexer cluster having three members. Is there any load balance will happen in indexer cluster for the search head requests?. I am not seeing any clear concept describing how the search head requests are handled by indexer cluster. All requests distributed evenly to indexer members or any other logic presents?.
