XiaoHongbo-Hope opened a new pull request, #1028: URL: https://github.com/apache/paimon-rust/pull/1028
### Purpose Add an optional, read-only OSS FileIO backend using Alibaba Cloud OSS C++ SDK v2. Select it with `fs.oss.impl=cpp`; OpenDAL remains the default. ### Changes - Add `storage-oss-cpp` (also in `storage-all`) and a separately built, versioned C ABI bridge. No SDK download or linking in normal Cargo builds. - Support HEAD, exact Range GET and paginated LIST. Reuse clients per bucket/FileIO; retain the existing REST credential-refresh and cache layers. - Bound blocking SDK requests (default 8), including after async cancellation. Reject reuse after fork and unsupported mutations. - Validate range status, offsets and body length; keep retries in the SDK and contain C++ exceptions. Do not expose signed requests or credentials in errors. - Add local HTTP integration tests, a pinned SDK CI job, and concise build/configuration documentation. ### Tests - Built the bridge against SDK 0.2.0, commit `c13a82038b0696f99c32f4e86b623ffcc9e62140`. - 5 backend tests passed, including 2 tests with the real SDK and a local HTTP fixture: partial-body retry, incorrect/short ranges, pagination, errors, credential replacement, concurrency and cancellation. - Existing I/O tests: 148 passed; RESTTokenFileIO tests: 4 passed. - `cargo fmt --all -- --check`, Clippy with `-D warnings`, and `git diff --check`. ### Scope Experimental read path only; no format or query API changes. The external bridge/SDK must be installed separately. This does not switch Python-side Blob downloads. No production OSS, throughput or long-tail improvement is claimed by these functional tests. -- This is an automated message from the Apache Git Service.
