In this video, you'll learn how to implement transactional batch operations in Azure Cosmos DB with FastAPI. Instead of making individual API calls that create bottlenecks, we'll build concurrent batch endpoints that group operations by partition key for maximum throughput.

What You'll Learn:
• Transactional batch fundamentals and why partition-based grouping is essential. The performance difference between individual operations versus concurrent batches.
• Async concurrent processing using asyncio.gather for multiple partitions
• Azure Cosmos DB batch API mechanics with operation tuples and execute_item_batch * FastAPI batch endpoints with clean dependency injection patterns
• Partition key strategy for optimal batch performance
• Data preparation techniques for Azure Cosmos DB (Decimal conversion, UUID generation) * Production-ready batch size limits and memory management
