Overall Activity Summary

The apache/opendal repository has seen significant activity over the past week, including new feature implementations, bug fixes, and ongoing discussions. Key areas of focus include enhancing language bindings (Python, C++, and Java), improving the CI pipeline, and advancing the object_store integration. The community is actively engaging in discussions and welcoming new contributors.

Key Ongoing Projects

• Python Bindings Enhancements

  • feat(bindings/python): Add feature groups for selective service building #6497 by @p1skiii introduces feature groups for selective service building in Python bindings, enabling more modular usage.
  • feat(bindings/python): allow Path in root #6490 by @asukaminato0721 allows Path objects to be used in the root argument, simplifying local usage.

• Object Store Integration

  • feat(core): support content_language in opendal::metadata and opendal:capability #6494 by @codephage2020 adds support for content_language in metadata and capability, addressing new feature: support content_language in opendal::metadata and opendal:capability #6470.
  • feat: allow using object_store as opendal's backend #6283 by @flaneur2020 enables the use of object_store as OpenDAL's backend, with advanced operations like parallel fetching and caching.

• C++ Bindings Improvements

  • Fix: make cpp binding build robust #6460 by @devillove084 aims to make the C++ binding build more robust, currently in draft.
  • fix(bindings/cpp): Add capability to fix failed tests #6488 by @asukaminato0721 fixes failed tests and enhances capabilities for C++ bindings.

• CI and Build System Updates

  • ci: update workflow nodejs version and remove corepack #6495 by @kingsword09 updates Node.js versions in CI workflows to maintain compatibility.
  • ci: Use ubuntu-24.04-arm for java release to address glibc issues #6486 by @Xuanwo addresses glibc compatibility issues for Java builds by using native platforms.

Priority Items

• Critical Bug Fixes

  • Release jobs for oli and node.js failed #6489 by @kingsword09 addresses failures in release jobs for Node.js and oli, requiring immediate attention to CI configurations.
  • bug: Java glibc version too high #6485 by @jackye1995 resolves Java glibc compatibility issues, ensuring broader platform support.

• Pending Reviews

  • feat(bindings/python): Add feature groups for selective service building #6497 by @p1skiii for Python feature groups is open and requires review to finalize modular service building.
  • feat(core): support content_language in opendal::metadata and opendal:capability #6494 by @codephage2020 for content_language support in metadata is a key feature awaiting approval.

Notable Discussions

• C Binding Async API Design

  • How to design opendal c binding's async api #6082: @asukaminato0721 initiated a discussion on designing async APIs for C bindings, exploring options like callbacks, state machines, and coroutine libraries.

• Optimizing Python Bindings

  • new feature: Python should accept Path for root argument #6479: @jayceslesar proposed allowing Path objects for the root argument in Python bindings, simplifying usage for local filesystems.

• Devcontainer Setup Optimization

  • new feature: devcontainer setup slow #6473: @dentiny suggested moving heavy installation steps from post-create scripts to Dockerfiles to improve setup speed.

Emerging Trends

• Focus on Language Bindings: Significant work is being done to enhance Python, C++, and Java bindings, making OpenDAL more accessible across programming ecosystems.
• Improved Metadata Handling: Features like content_language support and modular metadata extraction are being prioritized, reflecting a trend toward richer data capabilities.
• CI Pipeline Modernization: Updates to Node.js and Java workflows highlight the community's focus on maintaining compatibility and improving build reliability.

Good First Issues

• new feature: Allow s3 service to configure assume role's tags #4975: Allow S3 service to configure assume role's tags. This task involves adding support for assume-role tags in reqsign and is a great way to get familiar with the S3 backend.
• Implement Write Returns Metadata for all services #5693: Implement Write Returns Metadata for all services. Contributors can extend metadata extraction for various services, starting with simpler ones like fs.
• new feature: cpp binding enable feature by user #6250: Enable feature selection for C++ bindings. This involves allowing users to enable specific features, making it approachable for those familiar with C++ build systems.
• new feature: publish the source and lock files for binaries (oli, oay...) #6198: Publish source and lock files for binaries. Ideal for contributors interested in improving the build and release process.

We encourage new contributors to explore these issues and join the community in shaping the future of OpenDAL!
