Elasticsearch connection

You can create a connection asset for Elasticsearch in a project or in a catalog. If you have a Watson Machine Learning service instance, you can promote the connection asset from a project to a deployment space. 

Elasticsearch is a distributed, open source search and analytics engine. Use the Elasticsearch connection to access JSON documents in Elasticsearch indexes.
