A method and messaging system comprising a master broker computer system, a plurality of slave broker computer systems, and a plurality of event stores, for a broker computer system to change its status from a slave broker computer system to a master broker computer system.

Message broker system with parallel persistence

A message broker computer includes a master broker, a plurality of slave message brokers and event stores. A client system sends messages for processing to the master broker. The master broker generates a message event in response to receiving such a message, and distributes the message event in parallel to the slave brokers and the event stores. Each of the event stores store the message event in persistent storage, and notifies the master broker that the message event has been persisted. The master broker considers the message stabilized n a quorum of the event stores. As the master broker does not take action until a messaging event is stabilized, in the event of failover, a new master broker is able to re-construct a broker state of the old master with no loss of data.
