## What - Compare common prefixes eight bytes at a time. ## Why - Reduce work for long shared prefixes in DELTA_BYTE_ARRAY encoding. ## Implementation - Use little-endian word loads and trailing-zero count. - Keep byte-wise handling for short tails. ## Benchmark - AMD EPYC, isolated comparison, 0 allocations: 256-byte prefix 202 → 43 ns/op (4.7x); 900-byte prefix 565 → 155 ns/op (3.6x). -- This is an automated message from the Apache Git Service.
