Abstract
A database system may include an array of storage devices configured to store a plurality of database tables and a plurality of histograms. Each histogram may correspond to one or more columns of a database table. The database system may further include a processor in communication with the storage device. The processor may receive an indication that a histogram is to be rebuilt, wherein the histogram has a first number of intervals. The processor may determine at least one condition associated with a distribution of column values of at least one column in the histogram. The processor may determine a second number of histogram intervals based on the at least one condition. The processor may rebuild the histogram to include the second number of intervals. A method and computer-readable medium may also be implemented.
