Abstract
Metadata for a plurality of database storage regions within memory are merged, where the metadata for each storage region comprises an interval including first and second interval values indicating a value range for values within that storage region. The first and second interval values are examined to identify overlapping storage regions and produce a sum of overlapped storage regions. The sum of overlapped storage regions is compared to a threshold and the metadata of the overlapped storage regions are merged based on the comparison.
