Attachment Handlers

An Attachment Handler allows you to extract pieces of any incoming message and store them separately. As a message processes through a channel, multiple copies of it will be held in memory at once (for the raw / transformed / encoded versions of a message, etc.). Attachments are stored only once, so by using them you can greatly reduce your channels' memory footprint. These are configured in the Channel Properties section of the Summary Tab within the Edit Channel View.

By default the attachment handler is set to None, meaning no attachments will be extracted. To extract attachments choose an attachment handler type from the drop-down menu, and select the Properties button to configure the handler.
