title: what is the role of elected master elasticsearch (ELK Stack)
body: <ol>
  <li><p>What is the main purpose of elected master in ELK. If elected master to have only node.master enabled, node.data disabled and not allowed to take any searching and indexing requests. </p></li>
  <li><p>I have 3 node cluster in which 1 is elected master. If I have kibana as front end UI for querying data and logstash sending data to the cluster for indexing (for realtime log analysis) , Is it a good idea to send searching/indexing requests to other 2 master nodes apart from elected master. or select 1 node for searching or another node for indexing leaving elected master untouched. Please advice. </p></li>
  </ol>
  
  <p>Please suggest me what would be the best plan </p>
