Overview

You can configure a TDMQ connector to consume content in TDMQ message queues. A TDMQ connector is implemented in the pull pattern. It automatically pulls TDMQ content and routes events to relevant services through event rules. This document describes how to create a TDMQ connector and the structure of events generated by the TDMQ connector.
Note
Currently, a TDMQ connector can consume only content in TDMQ-Pulsar message queues.
