Problems solved by technology

[0007] There are two main problems in the existing HBase sharding method: the first fixed-value algorithm will cause hotspots, that is, when the amount of data is small, the data will be concentrated on one data shard on one server, and the read Low write efficiency and unbalanced cluster resource utilization
The second cubic algorithm will cause small file problems. According to the cubic algorithm, many small data fragments will be generated, which are essentially many small files. The efficiency of reading and writing queries on these small files is very low, which affects the cluster. performance

Abstract

The invention discloses a method and device for segmenting fragments, and relates to the technical field of computers. A specific embodiment of the method for segmenting fragments comprises the steps:obtaining the size of a maximum fragment of a current target table on a server; and if determining that the size of the maximum fragment is greater than a fragment size threshold, performing segmentation on the fragment, wherein the fragment size threshold value is obtained according to the number of fragments of the current target table on the server. According to the method and device for segmenting fragments, the utilization rate of cluster resources can be effectively improved, and the problem of data hotspots is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a method and device for slicing and splitting. Background technique [0002] HBase (HBase is a high-reliability, high-performance, column-oriented, and scalable distributed storage system, using HBase technology to build large-scale structured storage clusters on cheap servers.) technology has been widely used in the field of big data, Its characteristic is that the scale of the cluster can be expanded horizontally, and a large amount of data can be evenly distributed on each server of the cluster, so as to obtain very high read and write performance. However, the existing HBase data fragmentation management methods cannot effectively utilize cluster resources, and there are hot spots. [0003] There are two general methods for HBase sharding: [0004] The first, fixed-value algorithm, uses a fixed fragment size. For example: set each shard to be fixed at 50G, wh...
