Research direction
Start by reading the linked PIP-42 proposal, which defines the requested local sort and Parquet lookup optimizations for append tables. Then identify the affected append-table implementation and its existing lookup or sorting tests. Done means the proposal's optimizations are implemented and their behavior and performance are validated.
