Which of the following options describes the Snowpipe 429 error meaning?

• A. PipeName not recognized
• B. Invalid request due to an invalid format or limit exceeded
• C. Request rate limit exceeded
• D. Service temporarily unavailable

Answer: (C)

When Snowpipe returns a 429, it means you’re being throttled because you’ve sent requests faster than the service allows. This status signals a rate limit has been reached, so the system can’t process more requests at that moment and asks you to slow down.

In Snowpipe, requests come from things like ingestion notifications or API actions that trigger pipe operations. If these requests pile up beyond the allowed rate for your account or pipe, the service responds with this 429 to prevent overload. That’s why the option describing a rate-limit exceeded is the best fit here.

Other scenarios describe different problems: an unrecognized pipe name would indicate the resource isn’t found or the name is invalid, a broadly stated invalid format or limit exceeded isn’t as precise as a rate-limit signal, and a temporary service outage would typically map to a 503. The essence of a 429 is specifically throttling due to too many requests in a given window.

To recover, implement backoff with jitter and retry after increasing delays, and consider reducing ingestion burstiness, spreading out work, or adjusting concurrency or quotas if available. Monitor ingestion rates and adjust scheduling to avoid hitting the limit.
