# Which issue does this PR close? Related to #10308. # Rationale for this change Demonstrate how to use OpenDAL with Parquet's generic async I/O interfaces, alongside the existing object_store example. # What changes are included in this PR? Add an in-memory read/write example with AsyncFileReader and AsyncFileWriter adapters and a SpawnedReader demonstration. Point application developers to parquet_opendal for ready-made adapters. OpenDAL 0.59 is a development dependency with only the memory service enabled. # Are these changes tested? The example asserts that both ordinary and dedicated-runtime reads reproduce the written RecordBatch. Formatting and whitespace checks pass. Current runtime validation is blocked: `cargo run -p parquet --example opendal --features async` fails while compiling the published `opendal-core 0.59.0` package because `src/docs/mod.rs:34` includes the missing `../../../CHANGELOG.md`. This draft needs that upstream packaging issue resolved before the example can be validated with 0.59.0. # Are there any user-facing changes? A new example, runnable with `cargo run -p parquet --example opendal --features async`. No public API changes. OpenDAL 0.59 requires Rust 1.91, above this workspace's declared Rust 1.88 MSRV; this affects development targets that resolve/build the new dependency. -- This is an automated message from the Apache Git Service.
