Hi,
The ElasticSearchSink checks for the existence of an index template called " *metrics_template*". If this template does not exist, it is created. This template ensures that all strings used in metrics are set to not_analyzed and disables the _all field. So answers to your questions are *YES*. Please create an index template named "metrics_template" and allow the system to create index automatically. - Hao On Wed, Jan 3, 2018 at 6:58 PM, Lh Reddy, Kesava < [email protected]> wrote: > Hi, > > We are planning to dump storm metrics to elasticsearch (using > ElasticSearchSink).
