Execution and streaming
Core · Execution and streaming
Core principle — Keep long work bounded while still delivering useful progress to the client.Deadlines, cancellation, backpressure, SSE framing, and terminal states that behave under disconnects.
Key concepts
Backpressure
Bound buffers
Disconnect
Abort signal
Terminal
Done or error event
Boundary model
Ownership matrix
Engineering considerations
Streaming increases responsiveness but also keeps resources open longer; its lifecycle must be more explicit than a normal response.Design constraint A stream is a resource lease, not an infinite response.
