Key Ongoing Projects

• Aliyun OSS Enhancements

  • feat(services/oss): add support for security token for Aliyun OSS #6511 by @cavivie introduces support for security tokens in Aliyun OSS, improving access control flexibility.
  • feat(services/oss): allow users to specify endpoint addressing style #6504 by @howardlau1999 allows users to specify endpoint addressing styles for OSS, enabling custom CNAME and reverse proxy configurations.

• Object Store Backend Integration

  • feat: allow using object_store as opendal's backend #6283 by @flaneur2020 enables using object_store as OpenDAL's backend, unlocking advanced features like parallel fetching and caching.

• C++ Binding Improvements

  • feat(bindings/cpp): enable user-configurable features for storage services #6503 by @KinomotoMio implements user-configurable features for storage services, reducing binary size and improving build times.
  • bug: Memory leak detected in cpp binding CI (LeakSanitizer) #6505 (related issue) addresses memory leaks in the C++ binding CI pipeline, ensuring stability.

• Node.js Binding Fixes

  • fix(bindings/nodejs): Change expires param to bigint in presign methods #6506 by @kingsword09 updates the expires parameter in presign methods to use bigint, improving precision.
  • fix(bindings/nodejs): use value.prefetch instead of value.concurrent for prefetch option #6502 by @kingsword09 fixes the prefetch option in ReaderOptions to align with expected behavior.

• CI Pipeline Modernization

  • chore(ci): migrate etcd, memcached, redis, and redis-cluster images to new sources #6435 by @kingsword09 migrates CI images for etcd, memcached, and Redis to new sources, addressing Bitnami's upcoming restrictions on free image access.

Priority Items

• Critical Bug Fixes

  • bug: Memory leak detected in cpp binding CI (LeakSanitizer) #6505 by @KinomotoMio addresses memory leaks in the C++ binding CI pipeline, requiring immediate attention to ensure CI stability.
  • fix(services/azblob): Fix azblob base64 validation #6500 by @kenwoodjw fixes base64 validation for Azure Blob Storage, resolving a long-standing issue (AzBlob: Confusing error message if access_key can't be decoded as base-64 #4108).

• Pending Reviews

  • feat(services/oss): add support for security token for Aliyun OSS #6511 by @cavivie for Aliyun OSS security token support is a key feature awaiting review.
  • feat: allow using object_store as opendal's backend #6283 by @flaneur2020 for object_store backend integration needs final approval to unlock advanced storage capabilities.

Notable Discussions

• Migrating Bitnami Images and Long-term Maintenance Strategies

  • Migrating Bitnami Images and Long-term Maintenance Strategies #6510: @kingsword09 initiated a discussion on alternatives to legacy Bitnami images for CI, inviting community input on sustainable solutions.

• C++ Binding Memory Leaks

  • bug: Memory leak detected in cpp binding CI (LeakSanitizer) #6505: @KinomotoMio raised concerns about memory leaks detected in CI tests, with ongoing efforts to resolve the issue.

Emerging Trends

• Focus on Backend Flexibility: Multiple PRs (e.g., feat(services/oss): add support for security token for Aliyun OSS #6511, feat(services/oss): allow users to specify endpoint addressing style #6504, feat: allow using object_store as opendal's backend #6283) aim to enhance backend configurability, reflecting a trend toward more user-centric storage solutions.
• Improved Language Bindings: Significant updates to C++ and Node.js bindings indicate a push to make OpenDAL accessible across diverse programming ecosystems.
• CI Pipeline Sustainability: Efforts like chore(ci): migrate etcd, memcached, redis, and redis-cluster images to new sources #6435 highlight the community's focus on long-term CI stability and compatibility with external dependencies.

Good First Issues

• new feature: Allow s3 service to configure assume role's tags #4975: Add support for assume-role tags in S3. This task is a great way to get familiar with the S3 backend and its configuration.
• Implement Write Returns Metadata for all services #5693: Implement Write Returns Metadata for all services. Contributors can start with simpler services like fs to extend metadata extraction.
• new feature: cpp binding enable feature by user #6250: Enable feature selection for C++ bindings. Ideal for those familiar with C++ build systems, this task simplifies user-configurable builds.
• new feature: publish the source and lock files for binaries (oli, oay...) #6198: Publish source and lock files for binaries. This task is approachable for contributors interested in improving the build and release process.
• Tracking issues of RFC-5479: Context #5480: Refactor services to use the backend.rs and core.rs convention. A good entry point for contributors looking to improve code organization.
