DATA STORAGE METHOD AND SYSTEM EMPLOYING DISTRIBUTED DATABASE

摘要

A data storage method employing a distributed database, pertaining to the technical field of data processing. The distributed database comprises a proxy layer (101), a first data layer (102), and a second data layer (103). The method comprises: the proxy layer (101) receiving target data requested to be written, wherein the target data comprises at least a first attribute value and a second attribute value (S210); the proxy layer (101) allocating, according to the first attribute value, the target data to a first target data node in the first data layer (102), and allocating, according to the second attribute value, the target data to a second target data node in the second data layer (103) (S220); and the first target data node and the second target data node respectively storing the allocated target data (S230). The method reduces the number of data nodes involved in data reading, reduces workload and response time of a system, and improves system reliability.
