Abstract
Merging adjacent rows of a synopsis table so as to increase the effectiveness of the synopsis table regarding data skipping. Adjacent rows for merging are identified based on statistics regarding: (i) queries of the database; (ii) effectiveness of the synopsis table for data skipping; and (iii) usage of predicates in queries of the database. Once merged, the synopsis table is smaller, and more effective with respect to data skipping, while fewer computing resources (administrative, maintenance, memory, clock cycles, storage space, etc.) are needed to process the database queries.
