The Dameng analytical large-scale parallel processing cluster software (DMMPP) is a peer-to-peer shared-nothing parallel cluster component developed based on Dameng’s database management system. It supports organizing multiple DM8 nodes into a parallel computing network to provide unified database services. It can support a maximum of 1,024 nodes, as well as TB- to PB-grade data storage and analysis. It also provides high availability and the ability to expand dynamically, making it a cost-effective general solution for very large database applications. DMMPP distributes loads to multiple database server masters to realize the storage and processing of large-scale data. Adopting peer-to-peer shared-nothing architecture, every database server is named an EP, and every EP is its own independent database. Within this architecture, every EP node’s functions are exactly the same, allowing users to connect to any EP node within the DMMPP system and conduct data manipulation.
