Embodiment Construction
[0025] Aiming at the problems of poor availability and reliability and prone to single point of failure in the prior art when using relational database services, the embodiment of the present invention provides a local relational database node scheduling based on cloud computing platform scheme. Receive the SQL statement sent by the local development engine when debugging the application through the database agent module, and determine the database operation command contained in the SQL statement, and according to the preset operation type and the different types of database nodes contained in the local relational database node cluster Correspondence, determine the database node corresponding to the operation type represented by the database operation command, and finally send the database operation command contained in the SQL statement to the determined database node for execution, which can not only prevent developers from having to connect to the Internet in real time to ob...

The invention discloses a local relation type database node scheduling method based on a cloud computing platform. The local relation type database node scheduling method is used for solving the problems that in the prior art, when relation type database service is used, the usability and the reliability are poor and single-point faults are prone to occurring. The method comprises the steps that a database agent module receives an SQL statement sent by a local development engine when the local development engine debugs an application program and determines a database operation instruction included in the SQL statement; according to the preset corresponding relationships between operation types and various database nodes included in a local relation type database node cluster, the database node corresponding to the operation type represented by the database operation instruction is determined; the database operation instruction included in the SQL statement is sent to the determined database node to be executed. The invention further discloses a local relation type database node scheduling device based on the cloud computing platform.
Description
technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a node scheduling method and device of a local relational database based on a cloud computing platform. Background technique [0002] Cloud computing technology (cloud computing) is an important direction of current information technology development. It refers to the increase, use and delivery mode of related services based on the Internet, usually involving the provision of dynamically scalable and virtualized network resources through the Internet. Cloud computing technology is mainly divided into three levels in the process of use: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Among them, PaaS (Platform as a Service, platform as a service) refers to the platform for software development as a service, and provides various service resources to developers in an open manner, and charges reasonable fees for the s...
