Patent number: 8316373Abstract: Concurrent processing of business transaction data uses a time slice-centered scheme to cope with the situation where multiple requests demand a same resource at the same time. The method divides the processing time into multiple time slices, allocates each request to a corresponding time slice, and iteratively processing requests according to their corresponding time slices. The method does not require the requests to be processed one by one, and therefore does not cause a situation where other requests have to wait until the current request has been completely processed. Moreover, if a certain time slice has been allocated multiple requests of a same type, the requests are collectively processed as if they were a single request to reduce the frequencies of resource locking and unlocking, as well as the waiting time in a queue for resource access.Type: GrantFiled: July 23, 2009Date of Patent: November 20, 2012Assignee: Alibaba Group Holding LimitedInventors: Li Cheng, Xingjun Ni, Xu Zhao
