Embodiments of the present application provide a task allocation method and system. The method includes: analyzing at least one query pattern of a target task to acquire expected response time of the query pattern; estimating system cost information and estimated response time according to the query pattern and service description information; estimating node cost information of each processing node of a set of processing nodes in a computing system; selecting a processing node of the set of processing nodes according to the node cost information to allocate subtasks of the target task to the selected processing node; and determining an unallocated subtask in the target task to schedule the unallocated subtask according to the expected response time, the system cost information, and the estimated response time.

Task allocation method and system

A method and an apparatus for processing a retransmission request in distributed computing are disclosed. The method includes obtaining a retransmission request to be processed in distributed computing; determining a target copy partition corresponding to the retransmission request based on respective partition response time information of individual copy partitions; sending the retransmission request to the target copy partition. Compared with existing technologies, the present disclosure distinguishes each partition with one another based on a partition response time of the respective copy partition to determine a target copy partition corresponding to a retransmission request, thus selecting a copy with a better response time during retransmission, reducing a response time for the retransmission request and reducing an overall load of an associated cluster.
