Disabling the Federate plugin

Siren Federate allows a node to disable the plugin. This allows an Elasticsearch node to avoid loading all Federate modules and prevents it from being involved in any Federate tasks.

To enable this behavior:

  1. Set the federate.enabled node attribute to false.

    config/elasticsearch.yml:
    node.attr.federate.enabled: false

  2. Restart the node.

You must ensure that the required indices are allocated on Federate-enabled nodes. Documents residing on Federate-disabled nodes aren’t available when querying Federate. In other words, these documents are silently ignored and are without any feedback in the response.
