Business Event Processor

Overview

Of late, community has been building features like 'Workflow using datatables', 'Triggered SMS', 'Notifications' etc, also we have many more features in roadmap like 'Flagging of Accounts', 'Data Driven Authorisation', 'Tasks Framework' etc. In all of these features, there is one commonality, which is to listen on a business event on an entity and perform either additional validation or processing. Drawback being that on each such business event each of these additional processing/validation results in a Database query to check if any additional processing or validation is required. The more such features we continue to add the more we are slowing down the system by way of adding more and more DB calls whether required or not. Also we are adding more and more new APIs and related processing code which in my view is mundane as well as time consuming. This design proposal is an attempt to generalize all such features under one single framework and API modelling, thus reducing the calls to DB and also improving the turn-around time for feature addition.
