Abstract: A method and an apparatus for processing data are provided. The method includes: determining, in response to receiving an access request sent by a client and a target path in a complete binary tree, a time interval between the access request and a last access request as a second time interval, a value of a non-leaf node of the complete binary tree being related to a time interval of latest two access requests received by a metadata server, a leaf node being used to represent a virtual node in a distributed system; determining a change amount of a value of a node in the complete binary tree according to the target path and the second time interval; querying an access result according to the access request, and sending the access result to the client; and sending the change amount to a management server end.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for processing data. The method can include: determining, in response to receiving an access request, a time interval between the access request and a last access request as a first time interval; acquiring a preset complete binary tree from a management server end, a value of a non-leaf node of the complete binary tree being related to a time interval of latest two access requests received by a metadata server, a leaf node being used to represent a virtual node in a distributed system, and the virtual node corresponding to the metadata server; selecting a target path from the complete binary tree according to the first time interval; and sending the access request and the target path to a metadata server corresponding to a leaf node of the target path.

Abstract: An authority management method and device in a distributed environment, and a server are provided. The method includes: obtaining usage information of a user when the user uses an object storage product, the usage information including the user's behavior, status and feature; determining a matching degree between the usage information of the user and usage information predicted by a portrait model of the user; and applying a preset early warning mechanism to the user's access authorities according to the matching degree.
