Abstract

The invention discloses a data isolation and query method and device, and relates to the field of a database. The method comprises the steps of when data is stored, building and generating a primary key K1 according to a secondary key K2 and primary key generation parameters, then storing (K2, V) into a customized object (DO), and finally adopting a (K2, V) data storage mode to store key value data; correspondingly, when the data is queried, building and generating the primary key K1 according to the secondary key K2 and the primary key generation parameters, then searching for the customized object (DO) according to the primary key K1, and finally taking out a data value V in the customized object (DO) according to the secondary key K2, wherein the primary key K1 is a logic key of the customized object (DO), the secondary key K2 is a data key of the customized object (DO), and V is a data value of the customized object (DO). According to the data isolation and query method and device, the isolation function of the data in the database is achieved.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method and device for data isolation and query. Background technique [0002] Memory-based key-value schema databases are usually used in scenarios with high concurrency, high throughput, and low latency requirements, and performance is the core design requirement. In terms of management, common databases often only provide simple security password authentication, and do not provide user space, data isolation and other means, and at the same time have shortcomings in statistics for large coverage. [0003] In the production practice of big data operation enterprises, the characteristics of providing services to multiple customers at the same time and the need to share hardware resources to improve resource utilization inevitably require data isolation that distinguishes customizable scenarios for traditional in-memory databases. Contents of the invention [0004] A technical problem...
