What is Async Batch Processing?
Async batch processing is a technique for handling multiple AI API requests concurrently while maintaining optimal performance and resource utilization. Unlike traditional synchronous processing, async batch processing allows your system to continue processing other requests while waiting for API responses, dramatically increasing throughput.
Parallel Processing
Execute multiple API calls simultaneously to reduce overall latency by up to 90% compared to sequential processing.
Error Isolation
Individual API failures don't affect the entire batch. Failed requests can be retried or logged separately.
Resource Optimization
Better utilization of network and computational resources by eliminating idle time between requests.
Connection Pooling
Reuse HTTP connections for multiple requests, reducing connection overhead and improving performance.

Implementation Guide
Step 1: Basic Async Batch Setup
Start with a simple async batch processor using modern JavaScript or Python async/await patterns. This foundation handles the basic concurrency requirements while maintaining readability.
Step 2: Rate Limiting Integration
Implement rate limiting to respect API provider constraints. Use token bucket or leaky bucket algorithms to control request flow and prevent being rate-limited.
Step 3: Error Handling & Retry Logic
Add exponential backoff retry logic for failed requests. Implement circuit breakers to prevent cascading failures and protect downstream services.
Step 4: Performance Monitoring
Add metrics collection for latency, throughput, success rates, and error rates. Use this data to optimize batch sizes and concurrency levels.
