Abstract
A method comprising receiving a plurality of data records, storing the data records as data segments in a storage element, receiving a plurality of descriptors for each data segment, wherein each descriptor describes an aspect of data contained in the data segments, employing a first user-defined function to resolve a first minimum descriptor for each data segment and a first maximum descriptor for each data segment, composing a lightweight index for the data segments, wherein the lightweight index comprises the first minimum descriptor for each data segment and the first maximum descriptor for each data segment, and appending the lightweight index to the data segments in the storage element.
