Timeouts and Polling

Polling model

EuroAPI uses queue-based message retrieval.

• GET /sortation returns one message per call when available.
• GET /destination returns one message per call when available.

Long polling

Both endpoints support timeOut query parameter in seconds.

• Input range is clamped to 0..30
• 0 means immediate check
• Returns 204 when timeout expires with no message

Example:

GET /destination?timeOut=10

Practical guidance

• Use one active consumer per queue path per logical client.
• Tune polling/timeout based on throughput and latency goals.
• Monitor GET /status queue counters (Sortation Q, Destination Q).
