Abstract

A data store system includes a processor that may generate a hash value based on a hash function for each column value in a selected column of a data store table and may select a first domain and a second domain of hash values. The processor may determine a frequency value for each hash value within the first domain, generate a unique identifier for each hash value within the second domain, and determine at least one statistic on the selected column based on the frequency values and the unique identifiers. The processor may store the at least one statistic for use in a query plan. A method and computer-readable medium may also be implemented.
