Embodiment Construction

[0022] When the application wants to access the database in the distributed database system, it needs to establish a database connection (database connection), so that the database can be accessed, such as querying, adding, modifying and deleting the data in the database through SQL operations, and in Close the database connection when the operation is complete. For a complex database application, frequent establishment and shutdown of the database will greatly reduce system performance, increase system overhead, and even become a system bottleneck. Database connections become a finite and expensive resource.

[0023] In order to make reasonable use of resources such as database connections, a database connection pool technology has emerged. The basic idea of ​​the connection pool technology is to establish and store the database connection as an object in the memory when the system is initialized. When the application requests to access the database, instead of establishing ...

Abstract

The invention relates to an allocation and recovery method of database connections. According to the allocation and recovery method, a database connection pool is used; the database connection pool comprises a global connection pool and a logical connection pool; the global connection pool comprises queues; the logical connection pool comprises queue corresponding to all databases. According to the invention, the queue structure of two connection pools is used, so that the connection in the sequence corresponding to the least active database or the connection never used can be found rapidly through the global connection pool, and the full utilization of connection resources of all the databases can be ensured.

Description

technical field [0001] The invention relates to a method for allocating and reclaiming database connections. Background technique [0002] With the continuous development of the Internet, the amount of data on the Internet has increased dramatically. Traditional stand-alone databases have faced obvious bottlenecks in processing large-scale data. Major Internet companies have begun to study the implementation of distributed databases. [0003] In the implementation plan of distributed database, it includes the following two categories: one is the client solution, which introduces a new client to process data fragmentation; the other is the introduction of database middleware, which fragments data The processing is done by the middleware, and the application only needs to access the database middleware, and the whole access process is almost the same as accessing the original database. [0004] Among database middleware solutions, there are relatively many solutions for MySQL...
