Abstract
A system collects statistical data for a data page, divides the data page into parts, analyzes the data page and the statistical data, based on compression efficiency of one or more compression methods for each part of each page, to determine a compression method for each part of page, and compresses, based on the analyzing, the parts of the data page.
Claims20
A system comprising:
- a memory;
- and
- a processor in communication with the memory, the processor being configured to perform processes comprising:
- collecting statistical data for a data page;
- dividing the data page into parts;
- analyzing the data page and the statistical data, based on usage value for each part of each page, to determine a compression method for each part of page;
- and
- compressing, based on the analyzing, the parts of the data page.
A method comprising:
- collecting statistical data for a data page;
- dividing the data page into parts;
- analyzing the data page and the statistical data, based on usage value for each part of each page, to determine a compression method for each part of page;
- and
- compressing, based on the analyzing, the parts of the data page.
