Abstract

The invention discloses a log processing method of a multivariate data server. The log processing method of the multivariate data server includes that a log is transmitted to a secondary copy after a primary copy saves the log in an internal memory; the primary copy and the secondary copy respectively perform operation of logging equipment and metadata disc application; and an application ending message is sent to an opposite side after the primary copy and the secondary copy complete the operation of the metadata disc application. According to the technical scheme of the log processing method and a device of the multivariate data server, the availability and reliability of the system can be improved.

Description

technical field [0001] The present invention generally relates to a multivariate data server, and more specifically, relates to a log processing method and device for a multivariate data server. Background technique [0002] In order to ensure the consistency and atomicity of the multivariate data server, a log system is used to complete the data storage of metadata. In order to ensure the atomicity of data, the general principle adopted by modern log systems is the strategy of writing logs first and then writing to disk. In order to prevent the loss of metadata, the log can only be deleted after all the replicas are applied. Therefore, how to recycle the log device immediately is a very important issue in the multi-data server. [0003] Existing log systems such as the hadoop file system (HDFS) use regular application logs, and after the application ends, the log devices are recycled. In this method, when the master copy (the copy that provides data services in the metada...
