Summary
In this release we are excited to announce the new build recipes documentation for Powertools for AWS Lambda Python, which explains how to handle Rust and C bindings libraries, GLIBC compatibility, cross-platform builds, and architecture-specific dependencies.
We also improved the Parser utility models by adding detailed descriptions and examples illustrating AWS Lambda event structures.
⭐️ Congrats to @dcabib, @sreejaaryahi18, @Liam-DeVoe and @shrivarshapoojari for contributing to this project for the first time!
The build recipes documentation
The Python ecosystem is evolving with more Rust and C bindings for better performance, introducing new Lambda deployment challenges like GLIBC compatibility and cross-platform builds.
We've published updated Powertools build recipes that cover:
- Build tools: pip, Poetry, SAM, CDK, Pants
- Cross-platform deployment for macOS/Windows → Linux Lambda
- GLIBC compatibility across Amazon Linux runtime versions
- Troubleshooting common issues
- Performance tips to reduce cold starts and package size
- CI/CD examples with GitHub Actions and CodeBuild
