DISTRIBUTED DATABASE SYSTEM AND SELF-ADAPTATION METHOD THEREFOR

摘要

A distributed database system and a self-adaptation method therefor. The system comprises a control node, a client API and data nodes. The control node is configured to manage the data nodes of the system, calculate a data route of the system and broadcast the data route to the client API and the data nodes. The client API is configured to provide a data read/write interface for a data visitor, and forward a received data operation request to the corresponding data node according to the locally cached data route. Each data node is configured to store a data fragmentation, and process the data operation request according to the locally cached data route.
