# Which issue does this PR close? Closes #9161 # Rationale for this change This PR applies the feedback from #9116 to make the parquet reader documentation examples more concise and easier to follow. # What changes are included in this PR? Updated 3 documentation examples in `parquet/src/arrow/arrow_reader/mod.rs`: 1. **`with_schema` example 1** - Schema mapping with timestamp 2. **`with_schema` example 2** - Dictionary encoding preservation 3. **`with_virtual_columns` example** - Virtual columns for row numbers Changes in each example: - Replaced `tempfile::tempfile()` with `Vec::new()` for in-memory buffer - Added `use bytes::Bytes;` import - Changed `ArrowWriter::try_new(file.try_clone()?, ...)` to `ArrowWriter::try_new(&mut file, ...)` - Added `let file = Bytes::from(file);` to convert buffer for reading - Added `#` prefixes to hide setup/imports in rendered docs The async example in `async_reader/mod.rs` was intentionally left unchanged since it demonstrates `tokio::fs::File` usage. # Are there any user-facing changes? No functional changes, only documentation improvements to make examples smaller and cleaner in rendered docs. -- This is an automated message from the Apache Git Service.
