Document Type and Number:
WIPO Patent Application WO/2019/057000
Kind Code:
A1
Abstract:
A log writing method, apparatus and system. In this method, in the premise that the size of a physical sector in a log disk is greater than or equal to the sum of the size of log meta information and the size of a reference data block, when a log entry to be written is written into the log disk, the log entry to be written can be spliced to form a memory block by means of address alignment and data splicing, so that the log entry to be written can be written into the physical sector of the log disk in less IO operations, the required number of IO operations for writing the log entry into the log disk is reduced, and the execution efficiency for writing the log entry into the log disk is improved.
