R5D4 is an analytics engine built with the following goals in mind:

• Live analytics. i.e., Compute analytics data as the events occur (as opposed to querying the transaction database).
• Live definition update. i.e., Ability to add new definitions(new analytics) without stopping the engine.
• Asynchronous processing. i.e., Computing analytics should not block the transaction processor.
• Platform agnostic. i.e., Should be usable by PHP as well as Python projects.

• Defining Analytics
