Building Event-Driven Architectures: Top 5 Best Practices

What this post added

This post introduces two patterns for integrating Confluent Cloud with AWS Lambda to build event-driven applications: the fully managed AWS Lambda Sink Connector and native event source mapping (ESM). It details the benefits and considerations of each pattern, including throughput, latency, scaling, and error handling. Additionally, it provides five best practices for building event-driven architectures with Confluent and Lambda: batching calls to Lambda, implementing robust error handling in Lambda code to avoid duplicates and stalled partitions, using Lambda functions idempotently, and keeping long-lived connections to Kafka outside the handler for better efficiency.
