Elasticsearch is a popular search and analytics engine that exposes a large number of REST APIs.

To enable ingesting data, Observe implements a subset of the Bulk API, with the following caveats:

  • /{target}/_bulk endpoint is not supported.

  • update and delete actions are ignored.

For backward compatibility with existing Elasticsearch clients, the following endpoints were also implemented:

  • HEAD requests for /_template/{name} always return 200 OK. This avoids clients attempting to create templates. Templates are not necessary in Observe’s architecture.

  • requests to /_xpack endpoints return a 400 error. These requests are usually due to client misconfiguration, and this allows the request to fail in a more visible way.
