Embodiment Construction

[0087] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without violating the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

[0088] The present application provides a NoSQL database data storage method, device and electronic equipment, a NoSQL database data query method and device, and a fully combined multi-field rowKey generation method, device and electronic equipment. This application belongs to the technical scheme of storing multiple data in a NoSQL database without using an index table, and directly storing and querying data through rowKey. Specific embodiments of the present application will be described in detail below in conjunct...

Abstract

The present application provides a data storage method for a NoSQL database, comprising: acquiring a set number of fields including at least one non-repeated rowKey rowKey full combination and a field to be added; For each rowKey in the combination, perform the step of adding fields, including: adding the field to be added after the rowKey to generate a new rowKey; if the number of fields in the rowKey meets the set conditions , then add the field to be added before the rowKey and remove the last field in the rowKey to generate a new rowKey; obtain the data corresponding to each new rowKey generated, and store the data stored in a row corresponding to the new rowKey in the NoSQL database. The present application also provides a NoSQL database query method and a method for generating a full combination of multi-field rowKeys. The present application can solve the problem that the query time efficiency of the existing technical solution is low and the optimal solution of the full combination of rowKeys cannot be directly generated.

Description

technical field [0001] The present application relates to the technical field of computer database data storage and data query, in particular to a NoSQL database data storage and query method and device. The present application also relates to a method and device for generating a full combination of rowKeys. Background technique [0002] In the monitoring scenario of a large-scale distributed system, users often need to query monitoring data and its historical data. On the one hand, due to the huge amount of monitoring data, monitoring data is generally stored in NoSQL databases; on the other hand, since monitoring data can usually be described in multiple dimensions, there are many combinations of fields for query conditions . This adds to the complexity of storing and indexing monitoring data in the database. [0003] In order to quickly respond to the user's demand for querying monitoring data, most technical solutions adopt the method of exchanging space for time. De...
