Abstract: Techniques related to prefix compression are disclosed. Each value in a set of values has a prefix component and a suffix component. The set of values is divided into at least a first plurality of values and a second plurality of values. Compression of each plurality of values involves determining a prefix component that is shared by each value of the plurality of values. Compression further involves determining a plurality of suffix components belonging to the plurality of values. The prefix component is stored separately from the plurality of suffix components but contiguously with a suffix component of the plurality of suffix components. This enables the prefix component and the suffix component to be read as a value of the plurality of values.
