Distributed Database Design and Performance Tuing

it is necessary to design a distributed database for real-time data storage to meet the needs of rapid data collection, for the operation and maintenance of large and complex systems. The system adopts the distributed database integrated with three databases to meet the storage of different types of data such as structured data and time series data of the operation and maintenance system. Based on the characteristics of data collection, the system adopts three methods: horizontal database partitioning, horizontal table partitioning, and horizontal partitioning to reduce the amount of table data and meet the performance requirements of the system.
