What is a typical consequence of using the loadHistoryScan endpoint excessively in Snowpipe?

• A. API throttling (429 errors)
• B. Data corruption
• C. No effect
• D. Faster load times

Answer: (A)

Excessive calls to the loadHistoryScan endpoint trigger rate limiting. Snowpipe protects the service by restricting how many requests you can make in a given time window, so when you push beyond that limit you’ll receive 429 Too Many Requests responses. That throttling slows down the overall ingestion workflow rather than speeding it up, and it won’t cause data corruption. In practice, space out requests, implement backoff when you see 429s, or rely on the normal ingestion flow instead of hammering the endpoint.
