Unique

Most recent version: v1.0.0

See the changelog of this Action type here.

Overview

The Unique Action stores a list of unique values received from a given event field. An event will be sent out via an output port each time a new value is identified. Furthermore, you can configure a list of all the events stored in its memory to be sent periodically via a different port.

In order to configure this action, you must first link it to a Listener. Go to Building a Pipeline to learn how to link.
