Task scheduling method and device, server and storage medium

The invention provides a task scheduling method and device, a server and a storage medium. The method comprises the steps that the scheduling server determines a plurality of first tasks to be processed; the scheduling server determines an execution server corresponding to each first task; the scheduling server determines a cache region corresponding to each first task according to an execution server corresponding to each first task; and the scheduling server stores the plurality of first tasks to corresponding cache regions according to an overtime verification strategy and a repeated verification strategy, so that an execution server obtains the tasks from the corresponding cache regions and executes the tasks. The execution server determines N current tasks which are being executed at present; the execution server obtains M target tasks from a cache region corresponding to the execution server according to the N current tasks; the sum of M and N is smaller than or equal to a preset threshold value, and no
