RabbitMQ trigger

NOTE: RabbitMQ trigger is in tech-preview.

Reads messages from RabbitMQ queues.

Attributes

Path	Type	Description
exchangeName	string	The exchange that contains the queue
queueName	string	If specified, the trigger reads messages from this queue
topics	list of strings	If specified, the trigger creates a queue with a unique name and subscribes it to these topics
reconnectDuration	string of duration	The timeout when trying to reconnect to RabbitMQ. Default is 5 minutes.
reconnectInterval	string of duration	The interval to wait before reconnecting to RabbitMQ. Default is 15 seconds.
prefetchCount	int	The prefetch count of the broker channel. Default is 0.
durableExchange	bool	Define if the exchange is durable. Default is false.
durableQueue	bool	Define if the queue is durable. Default is false.

Note: topics and queueName are mutually exclusive. The trigger can either create to an existing queue specified by queueName or create its own queue, subscribing it to topics

Note: when running in Kubernetes / docker, the consumer name is the host name (pod name, e.g.: my-pod-1234) and the connection name is consisted of nuclio-<func-name>-<trigger-name> to allow differentiation between multiple functions consuming from the same server.
