DMS for RocketMQ Event Source

DMS for RocketMQ is a message queuing service that provides RocketMQ premium instances. If you create a RocketMQ trigger for a function, when a message is sent to a RocketMQ instance topic, FunctionGraph will retrieve the message and trigger the function to perform other operations.

For the use of RocketMQ triggers, please refer to Using a RocketMQ Trigger.
