linliu-code opened a new pull request, #644: URL: https://github.com/apache/hudi-rs/pull/644
**Stacked on #639–#643** — their commits appear here until they merge. **Review only the last commit.** - `reader_v2::row_serde` — the Arrow IPC pair the merge buffer uses to move a record to disk and back when it spills, plus the body-only variant that drops per-record schema framing. - `reader_v2::buffer::record_positions` — decodes the positions a log block carries for its records. ## New dependencies — the one thing to scrutinize here `base64` and `roaring`. Hudi stores record positions in a log block header as a **base64-encoded roaring bitmap**, so these are the storage format's own encoding rather than a design choice. Neither pulls a transitive tree of its own. Nothing reads positions yet — the position-based merge that uses them lands later.
