Regarding Mirth Donkey
 
Hi,

We are looking for an integration engine for our HL7/DICOM requirements and we are considering/evaluating Mirth as a potential option. Read that Mirth has replaced Mule with home grown messaging/routing engine 'donkey'. I have couple of questions.

1) One of the major concern that we have is regarding the size of the payload. What are the different capabilities available in donkey to deal with very large files which is not available in Mule ?

2) Is donkey available independently as a separate download/open source?

Thanks,
Antony.

Donkey has batching and attachment handler interfaces built-in. Batch adaptors can intercept large files and split them up while streaming (without reading the whole file in memory at once).

Attachment handlers can intercept a message before it's dispatched to a channel, extract attachment data (whatever that may be, an encoded PDF in an HL7 message, DICOM image slices, etc.), and store it separately so that it is not included during normal message processing. It even automatically breaks the attachment into chunks for efficient database storage. The attachment can then be retrieved and reattached to the message when you need it to be.

You can checkout the source code for only Donkey if you want.

Hi,
we were interested in the queueing system for Donkey. What's the technology used: ActiveMQ, RabbitMQ?!

Thanks

It's neither. It's using a completely custom database-backed queuing system with threads that poll for messages and handle them asynchronously. I'd recommend checking out the source code if you want to know more.
