Row-group pruning drops groups with missing maximum statistics · case 03

Row-group pruning drops groups with missing maximum statistics.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

Choose row groups that may satisfy an inclusive equality/range scan. Metadata [id,min,max,null_count,row_count] describes known integer values; unknown min/max cannot prove exclusion. Null-only and empty groups cannot satisfy a non-null range. Return candidate IDs without claiming every candidate contains a match.

Why this case matters

A bounded deterministic data engine model makes representation and changelog faults reproducible.
