Abstract

Disclosed herein are system, method, and computer program product embodiments for partition pruning via non-homogenous synopsis information. An embodiment operates by maintaining synopsis information for a data partition in accordance with a first synopsis strategy, monitoring performance of the synopsis information within a partition pruning system, determining that the performance of the synopsis information is insufficient, and updating the synopsis information in accordance with a second synopsis strategy better suited for the attributes of the data partition. In some embodiments, a first data partition of a partitioned data table may employ a first synopsis strategy and a second data partition of the partitioned data table may employ a second synopsis strategy.
