Dynamic task prioritization for in-memory databases

摘要

The present invention provides method and system, including computer program product, implement and provide atypical CPU time thread accesses using the technology for task to provide the Database Systems of back work. Particularly, the present invention relates to the method realized in such Database Systems, include the following steps: the queue database system with insertion task; And it executes the task and is inserted into the threads of queue back work Database Systems according to its sequence in the queue; It is characterized in that, the queue is a primary problem queue; And be, the method also includes following steps: distribution every class to respective priority; And because the task of the step of insertion to queue includes: the class that relevant each task and respective priority distribute to it.
