A payment method by a processing server to process payment that is independently performed between a user equipment and a payment channel server is provided. The method includes: generating, by the processing server, a payment order bound to a merchant order generated by a merchant device by determining a corresponding item ID, of a service and/or a product for purchase, that is registered with the payment channel server, the merchant order corresponding to the service and/or the product provided by the merchant device; obtaining, by the processing server, a payment voucher corresponding to the payment order; matching, by the processing server, based on the payment voucher, the merchant order bound to the payment order; and transmitting, by the processing server to the merchant device, based on the matched merchant order, a service/product providing notification for providing the service and/or the product to the user equipment.

Payment method and apparatus, related device, and system

A hash database configuration method and apparatus, where the method includes establishing an index area and a data area on a disk, where the index area includes p disk pages with an equal size, and receiving an allocation request of key-value pairs, allocating m keys in the key-value pairs to disk pages in the index area, and allocating n values in the key-value pairs to the data area, where m, n, and p are all integers greater than 1, and the efficiency of accessing the hash database is improved.

Hash database configuration method and apparatus

Embodiments of the present disclosure provide a data prefetching method, a node, and a system. The method includes: a first storage node receives a read request sent by a client, determines a to-be-prefetched data block and a second storage node where the to-be-prefetched data block resides according to a read data block and a set to-be-prefetched data block threshold, and sends a prefetching request to the second storage node, the prefetching request includes identification information of the to-be-prefetched data block, and the identification information is used to identify the to-be-prefetched data block; and the second storage node reads the to-be-prefetched data block from a disk according to the prefetching request, and stores the to-be-prefetched data block in a local buffer, so that the client reads the to-be-prefetched data block from the local buffer of the second storage node.
