Lambda Functions

ar-event-streaming-demo-dev-command

This Lambda receives the POST request to /command and publishes a "transaction-created" event. In a real world example, this event would be published by the command that handles the creation of the transaction. This lamdba simulates this.

ar-event-streaming-demo-dev-createMailbox

This Lambda reacts to the "transaction-created" event and creates a new mailbox based on the data included in the event. Once the mailbox is created, it signals this by publishing a "mailbox-created" event and includes details of the new mailbox.

ar-event-streaming-demo-dev-updateTransaction

This Lambda reacts to the "mailbox-created" event and updates the specified transaction with the mailbox details included in the event.
