Asynchronous Agent Execution
Quick Take
- In brief: Asynchronous agent execution lets a client start work and receive its result later.
- Useful for: Tasks that may take longer than one request or interaction.
- Main limit: Job status, cancellation, and persistence depend on the system.
Overview
A client starts a repository analysis and receives a job identifier. It can continue other work, then check for the result when the job finishes.
Core Definition
Asynchronous agent execution separates starting a task from receiving its final result. The system may return a job or session handle and report progress through polling, notifications, or another documented mechanism.
Background and Evolution
Long-running tasks can exceed the time a client keeps a request open. Asynchronous patterns let the client continue without waiting on one connection. They do not guarantee that a task survives a restart or can be resumed.
How It Works
- The client submits a task.
- The service accepts it and returns an identifier or status.
- The client checks status or receives an update.
- The service returns a result or error when available.
- The client handles cancellation, timeout, and retry according to the service contract.
Applications in Software Development and Testing
A test service can run a large suite while a developer reviews another change. The interface should show which revision was tested and whether the job completed, failed, or was cancelled.
Strengths and Limitations
The client can remain responsive while longer work runs. Asynchronous execution adds status handling, duplicate-request risks, and delayed failures. Persistence and retry behavior vary by service.
Comparison with Similar Terms
Synchronous execution keeps a request open for its result. Asynchronous execution returns control before the result is ready. A background agent describes where or how work runs; it may use asynchronous execution but is not the same concept.
Best Practices
Track the job identifier, task input, and code revision. Define timeout and cancellation behavior. Make retries safe against duplicate side effects. Show users the current status and final result.
Common Pitfalls
Do not assume a job persists after disconnection. Do not interpret a missing update as success. Check the result and the revision that produced it.
FAQ
Can an asynchronous job always be resumed after a client disconnects?
No. Resume and persistence behavior depend on the service. Check its contract and test disconnection cases.
