Abstract
Embodiments provide techniques for identifying unique data elements in data record, removing the unique data elements from the record, storing the record, and employing the removed, unique data as a key in an index into the data storage. When the record is retrieved based on the key in the index, the removed unique data elements is restored. Removal of the unique data elements from the records may enable more efficient compression of the records using compression algorithms that employ an external reference dictionary. In some embodiments, a combination of multiple, removed data elements may be employed as a key. In some embodiments, the removal and use of the unique data as an index key proceeds in a manner that is transparent to the data consuming user, process, or device.
