Description

After mailQueue and eventBus our latest usage of queuing system is to coordinate the execution of tasks across a James cluster.

The following components would need to be backed by pulsar:

• Task manager work queue (so far an exclusive consumer) which also includes listening for cancellation requests.

This would allow assembling a distributed task manager centered around Apache Pulsar.

Definition of done:

• Split the distributed task manager maven module by technologies: task-rabbitmq task-cassandra task-pulsar.
• Pass the work queue contract test
• Pass the distributed task manager contract test
