[0003] The setting of the corePoolSize parameter is very important. If the corePoolSize parameter is set too large, the thread pool will create many useless threads, thus wasting a lot of resources.
If the corePoolSize parameter is set too small, the thread pool cannot execute tasks in time, making many tasks need to wait, and even the task execution fails due to timeout
[0004] At present, the product of the experience value and the number of CPUs (Central Processing Unit, central processing unit) is usually set as the corePoolSize parameter, but the corePoolSize parameter set based on the experience value may not be suitable for different working scenarios of the device, and in turn, may cause the device to appear Fault

The invention relates to a method and device for setting the thread pool parameters, a computer device and a storage medium, and belongs to the technical field of computers. The method comprises the steps of estimating the degree of parallelism of each type of tasks at different moments based on the average execution duration and the execution frequency of each type of tasks, wherein the degree ofparallelism is the number of the tasks executed in parallel; and setting a thread pool core scale of a thread pool based on the degree of parallelism of each type of tasks at different moments. By adopting the method, the thread pool core scale can be set according to the statistical value corresponding to each type of tasks executed within the preset historical duration, and the set thread poolcore scale can be suitable for different working scenes of the devices, so that the method provided by the embodiment of the invention can reduce the device faults.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for setting thread pool parameters. Background technique [0002] The thread pool is a common thread management tool, which can perform operations such as creating threads, placing threads, and ending threads. When using the thread pool, you need to set the thread pool parameters. The core parameter of the thread pool can be corePoolSize (thread pool core size), and the corePoolSize parameter is used to limit the number of threads currently established by the thread pool. [0003] The setting of the corePoolSize parameter is very important. If the corePoolSize parameter is set too large, the thread pool will create many useless threads, thus wasting a lot of resources. If the corePoolSize parameter is set too small, the thread pool cannot execute tasks in time, causing many tasks to wait, and even task execution...
