摘要： 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, determining that a current memory block of a most recently added token to the compressed column store is the insertion block. It is determined that the maximum token value has been reached for the current memory block. A new virtual memory block is created using the current insertion block, and a token corresponding to the new value is stored in the new virtual memory block. In another embodiment, when it is determined a maximum number of token values that may be stored in a compressed column store has been reached for a data dictionary, the compressed column store is converted into a composite store include a flat store where the new value is stored.
