摘要
A data store system may include an array of persistent storage devices configured to store a plurality of data store tables. The data store system may further include a processor in communication with the storage device. The processor may receive a query containing a non-equality join condition on a first column from a first data store table and a second column on a second data store table. The processor may generate a bitmap based on the join condition. The bitmap indicate respective matches between the first column and second column in accordance with the non-equality join condition. The bitmap may also be used each time the non-equality join condition is present in another received query. A method and computer-readable medium may also be implemented.
