Abstract
Conventionally, in addition to indexing, a synopsis of a base table of a database is used to skip and compress data. However, scanning of the entire synopsis for all queries is required, which takes a long time when the synopsis gets significantly big in a large data warehouse. A method for efficient data skipping and compression through vertical partitioning of data is provided to eliminate the cost of synopsis storage overhead while enabling the synopsis search functionality.
