Establish the first processing step and the context carried with the message.
Messaging Systems
Pipes and Filters
Break processing into independent filters connected by channels. Each step performs one responsibility, making the flow easier to compose, test and evolve.

How Pipes and Filters works
The message moves through a coordinated sequence of processing steps and decisions.

Pipes and Filters
Step 1
Step 2
Result
Use Pipes and Filters to coordinate ordering, decisions and intermediate results.
Complete the flow or select the next step based on the accumulated state.
What this pattern helps you decide
Break processing into independent filters connected by channels. Each step performs one responsibility, making the flow easier to compose, test and evolve.
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
- Logic Apps actions
- Azure Functions chained by Service Bus
- APIM inbound/backend/outbound policy flow
How the analyzers can surface it
- APIM execution flow
- BizTalk pipeline and orchestration stages
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.
