Dandandan opened a new pull request, #684: URL: https://github.com/apache/arrow-rs-object-store/pull/684
## Summary - Adds an `io_uring` feature flag (linux-only, optional) that uses `io_uring` to batch all range reads in `get_ranges` into a single syscall - Instead of N separate `pread` calls, submits N `IORING_OP_READ` SQEs and calls `submit_and_wait` once — the kernel can then optimize I/O scheduling and reorder for disk locality - Falls back to the existing sequential `read_range` loop when the feature is not enabled ## Test plan - [x] `cargo check` passes without the feature (macOS/non-linux) - [ ] `cargo check --features io_uring` on Linux - [ ] `cargo test --features io_uring` on Linux — existing `get_range`/`get_ranges` tests exercise the new path - [ ] Benchmark with multiple small ranges on a large file to measure syscall reduction 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
