Abstract

The invention provides a log recording method and apparatus, relates to the field of log management, and solves the problem of poor system processing capability. The method comprises the steps of writing a task allocation cache queue group into a log file, wherein the cache queue group comprises at least two cache queues; selecting at least one cache queue in the cache queue group as a current cache queue; and writing log data in the current cache queue into the log file in a disk, and obtaining to-be-written log data by the cache queues, except the current cache queue, in the cache queue group. The technical scheme provided by the log recording method and apparatus is suitable for a high-concurrent log reading/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...
