Predicate-based range set generation

机译:基于谓词的范围集生成

摘要

A system may include a storage device configured to store a data store comprising data. The database system may further include a processor in communication with the storage device. The processor may receive a query that includes at least one predicate associated with the data. The processor may further determine that the at least one predicate is eligible to be converted to a range set predicate. The processor may further convert the at least one predicate to a range set predicate. The processor may further process the query with the range set predicate. A method and computer-readable medium may also be implemented.
