Mule 3.5.0 - Read large dat file and map to csv (in Mule CE)

Question

I'm looking for a way to build a Mule application that will read a large dat file (~800k rows) and map some of it's fields to a new csv file (with different headers) as output. I'm running the Community Edition of Mule so I'm unable to use the DataMapper tool. I've also looked at the CSV to Maps/Maps to CSV tools in conjunction with an in-memory DB, however these transformers also appear unavailable when using the Mule CE Server Runtime.

I need to package this application (as a war) and deploy it to an application server in the long-term, so I'm looking for a solution that would allow me to do that. I understand that even in EE the DataMapper tool still isn't fully supported by application servers. I've been stuck on this for a while now so any help or guidance would be greatly appreciated. Thanks in advance.

Take a look at FlatPack: http://flatpack.sourceforge.net/

From the doc:

FlatPack should integrate nicely with Mule, the open source choice for integration and SOA.
