Module zone_map 

Zone maps for data skipping during scans.

Zone maps store min/max/null_count metadata for each chunk of property data, allowing the query engine to skip chunks that can’t possibly match a predicate.

For example, if a chunk has min=50 and max=100, and the predicate is age < 30, the entire chunk can be skipped without reading any actual data.
