Abstract

The related compression storage method for great much data comprises: detecting CPU type to select matched storage strategy; saving one piece of record with integral information in website as the reference for other records; noting the reference record difference by increment means; removing the last-version data in history to realize the dynamic conversion for history and active data; according to frequency of data value, recoding data to calculate without decoding. This invention can improve query efficiency with less storage space.

Description

technical field

[0001] The present invention relates to data storage technology, in particular to a storage technology for massive data in a database management system (DBMS) using a multi-version concurrency control protocol (MVCC), specifically a method for compressing and storing massive data and an execution device . Background technique

[0002] The database storage subsystem is an important part of the database system. It is responsible for storing data on the storage medium and providing data access to the query processing subsystem. The storage method refers to the storage format of data on permanent media (such as disks, tapes) and the storage method on volatile media (such as ordinary memory).

[0003] Common storage methods are as follows:

[0004] 1. Conservative storage strategy: This is the traditional storage method [1]. Because some CPUs require the data in the memory to be stored aligned according to the data type, this method takes this part of the CPU i...
