Deterministic Message Processing in a Distributed Network

A system for message processing in a distributed network, the system comprising:

• first and second computer systems coupled to one another in the distributed network, each of the first and second computer systems comprising at least one processor and at least one memory in which computer-executable instructions are stored that, when executed by the at least one processor, implement a message operator configured to process messages arriving at the message operator to manage a data structure having a state determined via processing of the messages;
• wherein the message operator of the first computer system is configured to reroute unprocessed messages received by the message operator of the first computer system to the message operator of the second computer system such that the message operator of the second computer system establishes an order of an input message stream and processes the input message stream to establish a current state of the data structure arising from the input message stream, and
• wherein the message operator of the second computer system is configured to, once the current state is established, send the input message stream to the message operator of the first computer system in accordance with the established order such that the current state of the data structure is recreated by the message operator of the first computer system.
