Thanks for the question and using MS Q&A platform.
When dealing with latency issues in Databricks API calls, especially when sending parallel requests, here are some strategies:
- Optimize Data Processing: Ensure that your data processing pipelines are optimized. This includes using efficient data formats like Parquet or Delta Lake, and optimizing your Spark jobs.
- Asynchronous Processing: Implement asynchronous processing for your API calls. This allows your system to handle multiple requests simultaneously without waiting for each one to complete.
- Batching Requests: Instead of sending individual API requests, batch them together. This can reduce the overhead and improve overall performance.
- Caching: Use caching mechanisms to store frequently accessed data. This can significantly reduce the number of API calls and improve response times.
- Load Balancing: Distribute your API requests across multiple nodes or clusters to avoid overloading a single point.
- Monitoring and Logging: Set up comprehensive monitoring and logging to identify bottlenecks and optimize performance. Tools like Datadog or Azure Monitor can be helpful.
- Retry Logic: Implement retry logic with exponential backoff to handle transient failures and reduce the impact of latency spikes.
- Delta Live Tables (DLT): Consider using Delta Live Tables for low-latency data processing. DLT can help manage data freshness and query serving latency effectively
