Abstract
Disclosed herein are system, method, and computer program product embodiments for rollover strategies in an n-bit dictionary compressed column store. An embodiment operates by receiving a new value for addition to a compressed column store. It is determined that a maximum storage capacity for tokens in the compressed column store has been reached for the data dictionary. The compressed column store is converted into a composite store including the existing compressed column store and a newly created flat store. The new value is stored in the flat storage portion of the composite store.
