Fast Infoset DataSource Support?

Does BIRT support Fast Infoset DataSources out-of-the-box? We have a set of REST webservices that our BIRT reports are using as DataSources, but some of the XML is very large and takes quite awhile just to transfer over the wire.

Am I going to have to write a custom BIRT DataSource for this? Can I simply extend the XML DataSource? Where would I start?

At this point of time, I don't think Fast Infoset is supported OOTB. If you want this support, please file an
enhancement request

Somewhat related question... is the Birt XML source using SAX or DOM for reading the data?

BIRT XML data source is based on SAX, so it's able to handle large XML streams. I think this data source is a good start for you to base your custom data source on.
