Abstract

The invention provides a log recording method and device. It involves the field of log management; solves the problem of low system processing capacity. The method includes: assigning a cache queue group to a log file writing task, the cache queue group comprising at least two cache queues; selecting at least one cache queue in the cache queue group as a current cache queue; using the current cache queue The log data in is written to the log file in the disk, and at the same time, the cache queues in the cache queue group except the current cache queue obtain the log data to be written. The technical scheme provided by the invention is suitable for a high-concurrency log reading and writing environment, and realizes efficient and parallel log data cache writing.

Description

technical field [0001] The invention relates to the field of log management, in particular to a log recording method and device. Background technique [0002] In daily development, log records are essential. Writing logs to the same file can only be written by a single thread. Usually, a simple lock (lock) is used to ensure that only one thread writes to the same log file at the current moment, thereby ensuring the correctness of the log output. But the disadvantage of this method is also obvious, that is, the efficiency of the system will be very poor in the case of high concurrency. It is easy to cause system performance bottlenecks and reduce system processing capabilities. [0003] Even if the multi-threaded processing method is used to avoid the decline of system processing capacity, when multi-threaded log records are written, because the log records need to interact with disk I / O, the time for a single thread to occupy the lock will be prolonged, resulting in a larg...
