Key Ongoing Projects

Enhancing Bindings Across Languages

• Python Bindings: feat(bindings/python): Enhance Reader and Writer #6086 by @chitralverma enhances Reader and Writer functionalities, adding support for advanced read/write options.
• OCaml Bindings: feat(bindings/ocaml): add more blocking api for ocaml #6238 by @asukaminato0721 introduces additional blocking APIs for OCaml.
• C Bindings: feat(binding/c): Add support for logging #6201 by @asukaminato0721 adds logging support, improving debugging capabilities.
• Java Bindings: feat(bindings/java): Add StatOptions support for new options API #6255 by @geruh adds StatOptions support, aligning with the new options API outlined in RFC-6213.

Service-Specific Improvements

• Google Cloud Storage (GCS): feat(core): Implement list with deleted and versions for gcs #5548 by @hoslo implements listing deleted files and versions, enhancing GCS functionality.
• Azure Data Lake (Azdls): feat(services/azdls): Support parsing Azure Storage configs from connection strings #6212 by @DerGut adds support for parsing Azure Storage connection strings.

RFC Implementation

• Options API (RFC-6213): Progress continues with contributions like feat(bindings/java): Add StatOptions support for new options API #6255 and feat(bindings/java): Add ListOptions support for new options API #6246, focusing on unifying and simplifying the API.
• Glob Support (RFC-6209): Ongoing discussions and PRs are shaping this feature to improve file pattern matching capabilities.

Priority Items

Critical Bug Fixes

• Azure Blob Storage: bug(bindings/python): Python bindings can throw different error types for the same error code #6235 by @chitralverma addresses issues with the write_with_if_not_exists capability.
• Node.js Bindings: bug: es module not support #6237 by @besscroft resolves ES module compatibility issues, enabling smoother integration with Next.js.

High-Impact Features

• Python Bindings: feat(bindings/python): Enhance Reader and Writer #6086 by @chitralverma requires thorough review and testing to ensure compatibility across services.
• GCS Enhancements: feat(core): Implement list with deleted and versions for gcs #5548 by @hoslo needs validation for large-scale use cases to ensure robustness.

Notable Discussions

• New Users: New Users: vaultwarden, Unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs #6234 highlights VaultWarden's adoption of OpenDAL for S3 integrations. Shared by @Xuanwo, this showcases OpenDAL's growing ecosystem relevance.
• RFC Progress: new feature: Unify read/ write (and their option) APIs #6227 by @chitralverma proposes unifying read/write APIs to simplify the Operator interface and improve usability.
• Governance: [VOTE] Accept Reqsign as part of OpenDAL PMC #6261 initiates a vote to accept Reqsign as part of the OpenDAL PMC, reflecting the project's evolving governance.

Emerging Trends

1. API Simplification: A strong focus on unifying APIs across bindings and services, particularly through the adoption of the Options API (RFC-6213).
2. Increased Adoption: Projects like VaultWarden integrating OpenDAL demonstrate its growing relevance in the Rust ecosystem.
3. Cross-Language Enhancements: Significant improvements to bindings for Python, Java, C, and OCaml are enabling advanced features like async operations and logging.

Good First Issues

1. new feature: cpp binding enable feature by user #6250: Enable feature configuration for C++ bindings. This task involves allowing users to configure features via build options, ideal for contributors familiar with C++ and build systems.
2. new feature: publish the source and lock files for binaries (oli, oay...) #6198: Publish source and lock files for binaries (e.g., oli, oay). A straightforward task for contributors familiar with release processes and packaging.
3. 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. Contributors can pick a service and refactor its code structure to improve maintainability.
4. Implement Write Returns Metadata for all services #5693: Implement Write Returns Metadata for additional services. This task involves extracting metadata from write responses, suitable for contributors interested in service-specific enhancements.
