AWS Lambda Event Sourcing Architecture

I'd like to have a AWS lambda / event system that allows for a certain kind of flexability, here's what I need.

Events come in via HTTP post webhook with headers and body
1. Store {headers, body} in one main events table where the event is named what the action is e.g. 'orderCreate', this acts as a ledger of events, with the main columns name, data, created_at.
2. I'd like to build up the state of individual object, in their own table so for orders a table would exist with that name the event of a orderCreated the row is created and subsiquent orderDeleted the row is deleted.

I need a way to tap into this event and trigger some side-effect event, for instance if a orderCreated comes in to the system I also need to fire something when that comes in such as invoiceCreated I need a way to access the stream of all events and subscribe to the orderCreated and fire a invoiceCreated which ideally should repeat this process all over again

You can install the mcrypt PHP extension with homebrew and use it with the standard PHP installation that comes with OS X.

Install mcrypt:

brew install mcrypt

Install the php extension -- this installs the whole php 5.5, but you can still use the system-provided one by default Note: install the version compatible with whatever your OS X PHP version currently is (check with php -v)

brew install homebrew/php/php55-mcrypt
