DISTRIBUTED DATABASE MANAGING METHOD AND COMPOSITION NODE THEREOF SUPPORTING DYNAMIC SHARDING BASED ON THE METADATA AND DATA TRANSACTION QUANTITY

摘要

The present invention relates to one kind to support dynamic fragment function to consider that metadata and affairs occurrence quantity just constitute Node distribution formula database for managing distributed data base, provide it is a kind of support the flexible of distributed management data, continuous and automatic mode is distributed and is stored the data according to accumulation and hands in incident situation. The management method of the distributed data base according to the present invention, including selection database divide, and constitute distributed data base system, the transaction nodes based on size of data and a certain amount of upper generation between at least one database from the destination node of node; It generates, includes separating destination node with dividing destination node fragment strategy to be applied to the metamessage of segmentation object source Nodes and transaction log database data, wherein fragment strategy includes fragment key fragment function; And fragment, at least one new node of the segmentation object node of at least part of segmentation object node database data according to the fragment strategy of generation. ;The 2014 of copyright KIPO submissions
