Abstract

The invention discloses a data loading method for a clustering system, a data loading device for the clustering system and the clustering system, wherein the data loading method for the clustering system comprises the following steps that: a first server in the clustering system reads data in a database and caches the read data to obtain cache data; a second server in the clustering system reads the cache data; and the second server in the clustering system loads the read cache data. Through the data loading method, the data loading device and the clustering system, the effects of reducing the database operation pressure and further prolonging the service life of the database are achieved.

Description

technical field [0001] The present application relates to the field of cluster systems, in particular, to a data loading method and device for a cluster system and the cluster system. Background technique [0002] With the rapid development of the Internet and e-commerce industries, server systems in the Internet usually perform large-scale data calculations. The most typical scenarios are some applications that require a large amount of calculations, such as rule engines and classification algorithms. In order to improve the speed of data calculation, a cluster system is usually used as the server system. Among them, the cluster system is usually a single master (single master) + multiple workers (many workers) mode, and workers realize data storage, reading and writing, analysis and processing etc., the master saves some or all of the metadata, implements worker task assignment, status monitoring, load balancing, fault monitoring and fault recovery, etc. Master often uses...
