Described herein is a system and method for providing a messaging cluster with hybrid partitions. In accordance with an embodiment, a computer environment or messaging system includes a cluster of message brokers, which supports a hybrid of one or more fixed type partitions and/or on-demand type partitions. A message producer can be associated with a configuration that indicates a type of partition to be used for connection with that message producer. The cluster of message brokers assign to that connection a partition of the type indicated by the connection. Upon a load-balancing or failover of a message broker having active connections to message producers, those connections having an indication of fixed type partition are assigned to the same partition at a failed-over message broker, while those connections having an indication of on-demand type partition can be assigned to any on-demand partition at the failed-over message broker.

System and method for providing a messaging cluster with hybrid partitions

Systems and methods are provided, for use in a messaging subsystem, which supports flow control of messages between producers and consumers. A system can include at least one producer that is operable to send messages in a batch to one or more consumers via at least one destination; and one or more consumers that are operable to process messages received from the at least one producer via the at least one destination. The system can also include a message broker which includes the at least one destination and which manages communications between the at least one producer and the one or more consumers. The message broker includes a flow controller that is operable to monitor a producing rate and a consuming rate, and dynamically adjust a batch size of the batch at the at least one producer based on the producing rate and the consuming rate to communicate the messages more efficiently.
