I am building custom pipeline components for receive pipelines in BizTalk Server (2006 and 2009). I am building the components in a streaming fashion.

My question: for any single inbound message, if I have a disassembling component, when I create n messages from a single inbound message, will the message agent always use a single thread when reading the (body) streams and persisting the messages to the message box? I would think so, but confirmation would be helpful.

Say if I create five messages in the disassembler, will any of these messages be persisted sequentially from the same thread? Or could these messages be processed in parallel?

On Biztalk 2004 it was done on a single thread, see http://www.microsoft.com/belux/msdn/nl/community/columns/claessens/custompp.mspx for details.

It should be the same for latter versions of Biztalk:

  • There was not a big change in Biztalk 2006, compared with the change between 2002 and 2004.
  • How could this be implemented? If you have a non seekable stream, it is not possible to move around the stream, and therefore not possible to allocate different parts of the stream to different threads.

  • Your second bullet point doesn't answer the question. Because if I had a seekable stream, would the behavior be the same? –  May 21 '10 at 16:52
