Databricks 429 error
Databricks 429 error
A 429 error in Databricks typically indicates that you have exceeded the rate limit for API requests. This means you’ve sent too many requests within a given period. Here’s how to address it and find more information:
Understanding Rate Limits
- Databricks REST API: Databricks has specific rate limits for its REST API to prevent abuse and ensure fair usage. These limits vary depending on the endpoint and your subscription level.
- Other APIs: If you’re using other APIs within Databricks (e.g., MLflow), they may also have their rate limits.
Solutions and Troubleshooting
- Identify the API: Determine which API you’re using and what is causing the 429 error. Check your code, logs, or the Databricks UI for clues.
- Review Documentation: Consult the Databricks API documentation to understand the specific rate limits for the API in question. Look for information on request limits per second, minute, or hour.
- Implement Backoff and Retry: Introduce your code’s backoff and retry mechanism. When encountering a 429 error, wait for a short period (e.g., a few seconds) before retrying the request. Increase the waiting time exponentially on subsequent retries.
- Optimize Requests: Review your code to see if you can reduce the number of API requests you’re making—batch requests together where possible or cache results to avoid unnecessary calls.
- Contact Databricks Support: If you’re consistently hitting rate limits despite optimization efforts, contact Databricks support for assistance. They may be able to adjust your limits or provide further guidance.
