MERGING METADATA FOR DATABASE STORAGE REGIONS BASED ON OVERLAPPING RANGE VALUES

摘要

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.

1. A computer-implemented method of merging metadata for a plurality of storage regions within memory, wherein 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 computer-implemented method comprising:
examining the first and second interval values to identify overlapping storage regions and producing a sum of overlapped storage regions; and comparing the sum of overlapped storage regions to a threshold and merging the metadata of the overlapped storage regions based on the comparison.
