Abstract

Various embodiments of systems and methods for a transaction message collector are described herein. The message collector receives the message from a message producer. In one aspect, the message is stored in an active message bulk storage or a new active message bulk storage. In another aspect, after the message is stored in the message collector, a confirmation is sent from the message collector to the message producer informing the message producer that the message is stored in the message collector. In yet another aspect, the active message bulk storage is forwarded to a message consumer for consumption based upon meeting at least one of plurality of time or memory based conditions. In a further aspect, after the active message bulk storage is consumed by the message consumer a result of consumption of the active message bulk storage is created and sent to the message producer.
