Abstract: In a message processing method, a message stream platform receives a plurality of log messages from a production platform, and the plurality of log messages are used to record information about a first service executed by the production platform. The message stream platform stores the plurality of log messages in a log file based on time segments. Then, the message stream platform may send messages in a same time segment in the plurality of log files to a consumption platform based on the time segment mark. According to the message processing method, the messages in the same time segment in the plurality of log files may be sent to the consumption platform to ensure that the consumption platform obtains the log messages generated in the same time segment.

Abstract: A data access method in a file system comprises receiving a data access request including an identifier of a to-be-accessed node, obtaining access permission for the to-be-accessed node based on the identifier of the to-be-accessed node, wherein when a permission version number of the to-be-accessed node is not the latest in permission version numbers of all nodes indicated by path information of the to-be-accessed node in a file system, the access permission for the to-be-accessed node inherits a permission record corresponding to a parent node that is of the to-be-accessed node and that has a latest permission version number, and performing authentication based on the access permission for the to-be-accessed node, and accessing data of the to-be-accessed node after the authentication succeeds.
