title: Logstash to output events in Elasticsearch bulk API data format
body: <p>Is is possible to have Logstash to output events in Elasticsearch bulk API data format? </p>
  
  <p>The idea is to do some heavy parsing on many machines (without direct connectivity to the ES node) and then feed the data manually into ES. </p>
  
  <p>Thank for the help. </p>
