Channel Purger
Remove obsolete messages from a channel in a controlled way before a test, migration or operational reset.

How Channel Purger works
A rule decides whether a message continues through the normal flow or is removed from it.
Candidate message
Channel Purger
Accepted
Ignored / isolated
Apply Channel Purger to separate useful messages from unwanted or invalid ones.
Forward accepted messages and explicitly handle the rejected path.
What this pattern helps you decide
Remove obsolete messages from a channel in a controlled way before a test, migration or operational reset.
What happens when processing fails or the same message is delivered twice?
Where does state, correlation or routing configuration live?
How will operators trace the message and understand the decision path?
Where you may see it
- Service Bus purge utility
- Drain-and-delete test queue
- BizTalk cleanup procedure
How the analyzers can surface it
- Environment and test queue hygiene
- Stale message risk
Pattern detection is contextual. GateSift should present these as architectural signals, not claim a pattern is implemented solely because one policy statement or adapter exists.
