Abstract: This application provides a task processing method, a first server may receive a first task processing request sent by a client, and then determine information of a task engine that is used to processes the first task processing request. The information of the task engine may be used to establish a connection to the task engine. The first server may store the information of the task engine and an identifier of the client in correspondence into an external memory. After the first server is faulty, another server may determine the information of the task engine based on the information of the task engine and the identifier of the client that are stored correspondingly in the external memory, and establish a connection to the task engine based on the information of the task engine, to use the task engine to continue to process a task initiated by the client.

Abstract: The present application discloses a task processing method. In the case that a server is started, during the process of starting, the server determines a processing engine which can be warmed up from processing engines included by the server, i.e., a processing engine to be warmed up. After the processing engine to be warmed up is determined, resources are allocated to the processing engine to be warmed up such that the processing engine to be warmed up, when receiving a task processing request, utilizes the allocated resources to process a task indicated by the task processing request. That is, before a processing engine receives a task processing request, desired resources are allocated to the processing engine in advance such that the processing engine, when receiving the task processing request, can execute a task in time without waiting for resource allocation so as to improve the task execution efficiency.
