DEVELOPER DOCUMENTATION

Respect the actual limits

Published request and concurrency limits will depend on the operational API. This preview does not promise unlimited throughput.

Retry deliberately

Use documented retry timing and bounded backoff. Do not create an endless retry loop or ignore a limit response.

Control concurrency centrally

Several workers sharing one account can exceed a combined limit even if each worker appears conservative. Coordinate request budgets across the application.

Use bounded backoff

Follow documented retry timing when provided. Otherwise use a deliberately bounded strategy with jitter appropriate to the service contract. Set a maximum attempt count and surface exhausted work for review.

Measure useful throughput

Track completed records, latency, limit responses, and inconclusive results together. Sending more requests is not an improvement if it increases blocking or duplicate charges.
