When to use this pattern
Use this pattern when:
- The processing required by an application can easily be broken down into a set of independent steps.
- The processing steps performed by an application have different scalability requirements.
- You require the flexibility to allow reordering of the processing steps the application performs, or to allow the capability to add and remove steps.
- The system can benefit from distributing the processing for steps across different servers.
- You need a reliable solution that minimizes the effects of failure in a step while data is being processed.
