Elasticsearch Batch Source
- Robin Rielley
The Elasticsearch Batch source plugin is available in the Hub.
Plugin version: 1.10.1
Pulls documents from Elasticsearch according to the query specified by the user and converts each document to a Structured Record with the fields and schema specified by the user. The Elasticsearch server should be running prior to creating the application.
This source is used whenever you need to read data from Elasticsearch. For example, you may want to read in an index and type from Elasticsearch and store the data in an HBase table.
