**What** - Use stable radix sorting for large, single-chunk integer `sort_indices` inputs. **Why** - Comparator sorting is slow for large integer columns. **Implementation** - Add stable LSD passes over integer key bytes. - Keep the current sort for nulls, floats, multiple keys and multiple chunks. **Benchmark** - 65,536 Int64 values: comparator 18–21 ms -> radix 2.7–3.0 ms (about 6–7x faster in an isolated Go benchmark). -- This is an automated message from the Apache Git Service.
