Embodiment Construction

[0028] In order to avoid the problem that the executor repeatedly executes the same task in the process of migrating from the original lock to the new lock, the core idea of ​​the embodiment of the present invention is: for a task, as long as one of the original lock and the new lock is saved The executor does not execute the task corresponding to the key value of the task, so as to avoid repeating the same task during the lock migration process and save the resources consumed by executing the task. In the specific implementation, the embodiment of the present invention introduces a migration device, which is used to intercept the request for adding a key value sent by each executor to the original lock or a new lock during the lock migration process, and forward the request for adding a key value Give the original lock and the new lock, that is, add the key value corresponding to the same task to the original lock and the new lock at the same time. When the new lock returns an...

Abstract

The invention discloses a lock migration method and device used for solving the problem that resources consumed for working tasks are wasted due to the fact that the tasks work for two times in the lock migration process in the prior art. When each worker is migrated from a first lock to a second lock through the migration device, a lock fetching target address of each worker is modified to an address of the migration device, a request for adding a key value and sent from each worker is received, and the received request is sent to the first lock and the second lock; when a received result returned by the second lock is an existence result, the existence result is returned to the worker; when the received result returned by the second lock is not the existence result, a received result returned by the first lock is returned to the worker, and the migration device modifies the lock fetching address of each worker to an address of the second lock. Through the method, the same tasks are prevented from being worked repeatedly in the process that each worker is migrated from the first lock to the second lock.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a lock migration method and device. Background technique [0002] At present, when the task processing system processes a batch of tasks, it will store these tasks in multiple task queues at the same time. The tasks stored in each task queue are the same, and each task queue consists of at least one executor (worker) To execute tasks in the task queue, such as figure 1 shown. [0003] figure 1 It is a schematic diagram of processing tasks through multiple task queues and workers in the prior art. The task processing system includes 3 task queues, and tasks in each task queue are executed by 1 worker. When executing a task, the user can add a task to the task queue through the client, and the client adds the same task to three task queues, and then the worker obtains the task from the task queue and executes it. [0004] due to figure 1 In the task processing...
