Embodiment Construction

[0060] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0061] This embodiment provides a distributed file system indexing method based on log merging, such as figure 1 As shown, the log merge-based distributed file system indexing method includes:

[0062] S101. When a file operation occurs, record the file operation information and write it into a log, the file operation information includes the type of file operation and the time when the file operation occurred, and when the type of file operation is a move operation, after recording the file After the operation information is written to the log, the file operation metadata information is created immediately.

[0063] All operation objects in this embodiment can be files or folders unless otherwise specified. For example, "file oper...

Abstract

The invention discloses a distributed file system index method and device based on log merging. Through the metadata server of the distributed file system, when the logs are merged, the file operationmetadata information is constructed and written into the storage unit, then the operation metadata information in the storage unit is read and parsed, finally, the file index operation is executed, the corresponding index is established, and the processed object is deleted. The invention can solve the problems of missing index, poor compatibility of client end, inability to incrementally build file index, long construction time and low efficiency.
