Receive messages that belong to the same logical group.
Message Routing
Resequencer
Buffer related messages and release them in the intended sequence based on sequence numbers or ordering rules.
How can we get a stream of related but out-of-sequence messages back into the correct order?Adapted from Enterprise Integration Patterns under CC BY 3.0. The visualization and explanatory content on this page are original GateSift material.

How Resequencer works
Several related messages are collected and turned into one coordinated result.
Related messages
Resequencer
Combined result
Use Resequencer to correlate, hold and decide when the group is complete.
Publish the combined or correctly ordered result.
What this pattern helps you decide
Buffer related messages and release them in the intended sequence based on sequence numbers or ordering rules.
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 sessions
- Durable Functions state
- Ordered BizTalk orchestration processing
How the analyzers can surface it
- Ordered delivery settings
- Sequence metadata
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.
