AWS Lambda now supports formatted Kafka events 🚀☁️ #81
Cloudflare Containers now in public beta
In the previous issue, Routing Rules for REST APIs 🚀☁️ #80, we looked into how the new API Gateway Routing Rules made the news.
AWS Lambda Functions just announced the support for formatted Kafka events with JSON Schema, Avro, and Protobuf which can now be integrated into your Schema Registry on Confluent and also AWS Glue Schema Registry. This brings about the abstraction for no more deserialization code to support different schema definitions and with in-built schema validation and event filtering.
Lambda Powertools also now supports Kafka utilities in Python, TypeScript, Java, and .NET.
If you are already familiar with Lambda event filtering, this support with formatted Kafka events now enables a smarter way to define event filters, making your Lambda function executions more cost-effective.
