## MQTT Consumer CoordinatorManager

CoordinatorManager class is manager class for mqtt consumer. It lets you connect to a MQTT server and subscribe to multiple topics. It gives you on_message callback for actions after receiving new message.

` >>> from mqtt import CoordinatorManager >>> >>> manager = CoordinatorManager('my-manager', '') >>> manager.start() >>> >>> consumer = manager.coordinated_consumer >>> consumer.on_message = on_message  # Pass callback name here. >>> consumer.subscribe("house/bulb") >>> consumer.poll(100)    # Batch message reading construct for streaming purpose `

` # Disconnect and stop consuming >>> consumer.disconnect() >>> manager.stop() `

There are 2 methods for consuming events, - registering for on_message - Reading messages in batches. Batches are internally stored in memory, and not stored on persistent disc for now.

## MQTT Producer CoordinatedProducer

` >>> from mqtt import CoordinatedProducer >>> producer = CoordinatedProducer('') >>> producer.publish_on_partition("house/bulb", "on") # Message will be published on random partition >>> producer.publish_on_partition("house/bulb", "on", partition=5) # Message will be published on 5th partition >>> producer.publish_on_partition("house/bulb", "on", partition_key='message_key') # All messages with partition_key will be published on same partition. `
