Log execution method and apparatus, computer device and storage medium

A computer device, comprising one or more processors and one or more memories storing at least one computer program, the at least one computer program being loaded and executed by the one or more processors to implement:

• circularly scanning a log execution active window, the log execution active window comprising a plurality of logs which are not executed, and all the logs before the log execution active window having been executed;
• acquiring a conflict verification result of a log in the log execution active window based on storage range information of the log, the storage range information indicating a storage range of the log and a storage range of a target number of logs before the log, and the target number being equal to a size of the log execution active window;
• and
• executing the log if the conflict verification result is no conflict, comprising:
• writing, by the one or more processors, the business data corresponding to the logs stored in a log list-to-be-executed into a volatile storage medium or a non-volatile storage medium stored in the one or more memories;
• adding, by the one or more processors, the logs corresponding to the business data written to the volatile storage medium to an executed log list in the one or more memories, wherein different state parameters are set in the executed log list for logs in the one or more memories, of which the business data is not written to the non-volatile storage medium, and for logs, of which the business data is written to the non-volatile storage medium, respectively;
• and
• after a crash event occurs in the distributed storage system, acquiring, by the one or more processors, when the distributed storage system is restarted, a plurality of logs-to-be-restored from the executed log list based on the state parameters, and restoring business data corresponding to the plurality of logs-to-be-restored to the volatile storage medium in the one or more memories in sequence based on a storage order of the plurality of logs-to-be-restored in the executed log list.

A non-transitory computer readable storage medium, storing at least one computer program, the at least one computer program being loaded and executed by a processor to implement:

• circularly scanning a log execution active window, the log execution active window comprising a plurality of logs which are not executed, and all the logs before the log execution active window having been executed;
• acquiring a conflict verification result of a log in the log execution active window based on storage range information of the log, the storage range information indicating a storage range of the log and a storage range of a target number of logs before the log, and the target number being equal to a size of the log execution active window;
• and
• executing the log if the conflict verification result is no conflict, comprising:
• writing, by the processor, the business data corresponding to the logs stored in a log list-to-be-executed into a volatile storage medium or a non-volatile storage medium stored;
• adding, by the processor, the logs corresponding to the business data written to the volatile storage medium to an executed log list, wherein different state parameters are set in the executed log list for logs, of which the business data is not written to the non-volatile storage medium, and for logs, of which the business data is written to the non-volatile storage medium, respectively;
• and
• after a crash event occurs in the distributed storage system, acquiring, by the processor, when the distributed storage system is restarted, a plurality of logs-to-be-restored from the executed log list based on the state parameters, and restoring business data corresponding to the plurality of logs-to-be-restored to the volatile storage medium in sequence based on a storage order of the plurality of logs-to-be-restored in the executed log list.
