Abstract

The invention discloses a distributed database parallel processing system. The technical scheme is: a distributed parallel database controllable redundancy structure is adopted, and different types of database server nodes are used (full database servers, non-full database servers and void database servers). The database cluster mainly comprises non-full database servers which store partial data of the database cluster to share the work load; and multiple non-full servers constitute multiple complete data sets through the void database servers which ensure the completion of the data sets in function. The full database server can independently provide the completion of the data sets. The void database servers select server nodes in the database cluster to form a star network covering all data and used for retrieving all data in the database cluster and dynamically linking the data areas on multiple database server nodes.

Description

technical field

[0001] The invention relates to a database system, in particular to a distributed database parallel processing system with controllable data redundancy, which simultaneously improves database data processing performance and database reliability. Background technique

[0002] High-speed database data processing performance and high database reliability are two important indicators of commercial database systems. In order to provide customers with fast, timely, stable and reliable services, commercial database systems have very high requirements for these two indicators. Under the limitation of existing software and hardware conditions, the traditional method can only improve another performance index at the expense of one performance index.

[0003] In order to improve the processing performance of the database system, the existing database system usually selects as fast and large-capacity hardware devices as possible (such as processors, memory, system bus an...
