# Deploying a Sinatra app to Heroku

## Database
The location of the database Heroku provides can be found in the environment
variable DATABASE_URL. Check the configure-block of toodeloo.rb for an example
on how to use this.

## Server
Heroku is serving your apps with thin, with means you have all your thin goodness available,
such as EventMachine.

Spring Integration Channels

Point-to-Point Channel (ie. only one consumer will receive the message)

• QueueChannel - Most basic one, receiver has to call the 'receive' method with timeout optionally
• PriorityChannel - Allows the endpoint to receive messages in a specified priority.
• RendezvousChannel - Sender will be bloqued until the receiver retrieves the msg from the channel
• DirectChannel (default) - Push messages but only one receiver can obtain the message - handleMessage will be perfomed within the sender's thread before send() method returns. Transactional
• ExecutorChannel - Similar to DirectChannel, but dispatching of the message happends in an instance of TaskExecutor (different to sender's thread), so no transactional support.
• NullChannel - Used for testing, send() method returns TRUE and receive() method always null.
