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 a method of managing a distributed database and constituent nodes of the database. According to the present invention, it is possible to perform flexible, automatic, and dynamic sharding that can sense whether a specific node needs to be sharded, and can automatically apply an optimal sharding strategy to be applied to database sharding or provide the optimal sharding strategy to at least a manager, by establishing an optimal measure on the basis of the database configuration, the data size, and the transaction quantity for each data.
