Chapter 22. ElasticSearch Index Sink

Stores JSON-formatted data into ElasticSearch.

The input data must be formatted in JSON according to the requirements of the index.

If you specify the certificate property, you must base64 encode it before you pass it as a parameter.

In the header, you can set the following properties:

  • indexId / ce-indexid: The index ID for ElasticSearch.
  • indexName / ce-indexname: The index name for ElasticSearch.

If you do not set a property in the header, the Kamelet uses the exchange ID for the index setting.
