Notable Discussions

• New Committer Announcement:

  • [ANNOUNCE] New OpenDAL Committer: Kingsword #6458: @kingsword09 has been welcomed as a new committer to the project.

• Optimizing C++ Bindings:

  • Topic: Optimizing the C++ Binding #6035: Discussion led by @deadlinefen on improving the C++ bindings, including support for async features and idiomatic APIs.

• Exploring OpenDAL File System:

  • Crazy Ideas: OpenDAL File System #2952: A discussion on the feasibility of building a file system using OpenDAL, led by @Xuanwo.

Emerging Trends

• Focus on object_store Integration: Significant efforts are being made to align OpenDAL's object_store implementation with advanced features like conditional copy and multipart uploads.
• Improved Contributor Recognition: The community is actively recognizing contributions, as seen in the announcement of a new committer.
• Standardization in Bindings: The adoption of consistent naming conventions and enhanced APIs in C++ bindings reflects a trend toward improving usability across languages.

Good First Issues

• Implement Write Returns Metadata for all services #5693: Implement Write Returns Metadata for all services. This involves extracting metadata from write responses and is a great way to get familiar with OpenDAL's service architecture.
• new feature: cpp binding enable feature by user #6250: Enable feature selection for C++ bindings. This task involves allowing users to enable specific features, making it approachable for contributors 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. This issue is ideal for contributors interested in improving the build and release process.
• Tracking issue: Refactor services to use the backend.rs and core.rs convention #5702: Refactor services to use the backend.rs and core.rs convention. A straightforward task to improve code organization and maintainability.
• Tracking issues of RFC-5479: Context #5480: Complete the implementation of RFC-5479: Context. This involves finalizing the context feature, which is foundational to many OpenDAL operations.
