Abstract
In a database system, wherein data is stored as objects within an object storage system, a system and method for estimating object cardinality, determining query execution plan costs, and selecting a query plan for execution by the database system. Multiple object cardinality estimation approaches for estimating the number of objects to be accessed for a given query condition on a column of a relation composed of a set of objects, where each object maintains the minimum value and the maximum value of individual columns are presented. A set of global statistics is also maintained, consisting of the total number of objects and the minimum and maximum values of individual columns. The object cardinality estimation is determined based on the global statistics without retrieving individual object-level statistics.
