Really nice and clever trick. Pushing the query bounds into the encoded domain once so the existing SIMD kernel can run unmodified on packed values is very clean, and the overflow fallback is a nice escape hatch. It also got me thinking about other filter pushdown opportunities. Anywhere we have an invertible monotone transform between stored and decoded values (delta + scale, ordinal dictionaries, scaled values,...) the same idea should apply: transform the predicate once on the cold path so the hot path keeps working on raw codes. -- This is an automated message from the Apache Git Service.
