I was intrigued the other day about how maps were behaving in BizTalk Server 2004 with regard to potential memory problems. BizTalk Server 2004 gives us great large message support through streaming messages into the message box. However, what if we specify a map in the Receive port, or indeed anywhere in BizTalk (Orchestration or Send Port)?
Well, BizTalk implements maps as XSLT stylesheets, and the way I understand it, the code uses the XslTransform class to perform the transformation and will load the input message into the DOM. This will require a significant memory footprint if the message is large!
This is often overlooked and is worth pointing out...
