METHOD FOR COMPRESSING DATABASE ON PER-UNIT COLUMN BASIS

摘要

According to an embodiment of the present invention, disclosed is a method for compressing a database on a per-unit column basis, which is performed by a computing device including at least one processor and main memory storing instructions adapted to be performed by the processor. The method for compressing a database on a per-unit column basis may comprise the steps of: determining the first number of rows, for which a compression unit is to be generated, in at least one column disposed in a table of a database; generating a first compression unit by compressing the determined first number rows; comparing a size of the first compression unit with a size of an extent; and determining the second number of rows, for which the compression unit is to be generated, in at least one column based on a result of the comparison.;COPYRIGHT KIPO 2017
