Methods, systems, and computer readable media for request response processing

A method for request response processing, the method comprising:

• at a central messaging bus implemented on a distributed computing system comprising a plurality of processors:
• establishing a request topic and a response topic for distributing a plurality of messages between a plurality of clients and a plurality of services executing on the distributed computing system;
• posting, in the request topic, a plurality of request messages from the plurality of clients, each client being associated with one or more unique client identifiers, each request message including one of the one or more unique client identifiers for the respective client posting the request message, wherein the plurality of services consume the request messages from the request topic;
• and
• posting, in the response topic, a plurality of response messages from the plurality of services responsive to the request messages, wherein the plurality of services post the response messages to a plurality of response partitions of the response topic using the unique client identifiers, and wherein the plurality of clients consume the response messages using the unique client identifiers to ensure that each client consumes a respective responsive message responsive to a respective request message from the client;
• for each client of the plurality of clients, determining each unique client identifier for the client based on a hash of an account identifier and a total number of partitions of the request topic.

A non-transitory computer readable medium comprising computer executable instructions embodied in the non-transitory computer readable medium that when executed by at least one processor of at least one computer cause the at least one computer to perform steps comprising:

• at a central messaging bus implemented on a distributed computing system comprising a plurality of processors:
• establishing a request topic and a response topic for distributing a plurality of messages between a plurality of clients and a plurality of services executing on the distributed computing system;
• posting, in the request topic, a plurality of request messages from the plurality of clients, each client being associated with one or more unique client identifiers, each request message including one of the one or more unique client identifiers for the respective client posting the request message, wherein the plurality of services consume the request messages from the request topic;
• and
• posting, in the response topic, a plurality of response messages from the plurality of services responsive to the request messages, wherein the plurality of services post the response messages to a plurality of response partitions of the response topic using the unique client identifiers, and wherein the plurality of clients consume the response messages using the unique client identifiers to ensure that each client consumes a respective responsive message responsive to a respective request message from the client;
• and
• for each client of the plurality of clients, determining each unique client identifier for the client based on a hash of an account identifier and a total number of partitions of the request topic.
