Message management using graph-based models

An overlay system, comprising:

• a storage element configured to store an executable graph-based model that comprises a plurality of message nodes and a first plurality of analytics overlay nodes, with each message node having a first set of analytics overlay nodes associated therewith, wherein each message node represents a message of a plurality of messages and has a composition that includes data and transactional information associated with the message, wherein the plurality of messages correspond to messages communicated between a plurality of modules of the overlay system, and wherein each analytics overlay node, of the first set of analytics overlay nodes, is configured to execute a set of analytics operations on the composition of the corresponding message node;
• and
• processing circuitry that is coupled to the storage element, and configured to:
• generate the executable graph-based model based on the plurality of messages;
• instantiate, for the generation of the executable graph-based model, one message node for each message of the plurality of messages, wherein the generated executable graph-based model includes the plurality of message nodes based on the instantiation;
• store the executable graph-based model in the storage element;
• receive a first stimulus associated with the overlay system;
• identify, in the executable graph-based model, based on a context of the first stimulus, (i) one or more analytics overlay nodes, of the first plurality of analytics overlay nodes, to perform analytics associated with the first stimulus and (ii) one or more message nodes, of the plurality of message nodes, for which the analytics is to be performed, wherein the one or more analytics overlay nodes comprise at least one of the first set of analytics overlay nodes of each message node of the one or more message nodes;
• and
• execute an operation associated with the first stimulus based on the one or more analytics overlay nodes and the one or more message nodes.
