Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] One of the main ideas of this application includes: removing the cache in the Ceph plug-in layer, that is, not setting the cache in the Cehp plug-in layer, reducing the level of data reading, and directly establishing the data reading / returning relationship between the HBase client and the Cehp system, Improve data reading efficiency.

[0028] Such as figure 1 As shown, it shows a flow chart of a data reading method provided by the present application, including:

Abstract

The invention provides a method and system for data reading. The method comprises the steps that an Hbase client terminal directly sends a data reading request to a Cehp system through a Cehp plug-in, wherein the data reading request comprises identification of target data and zone information of the target data; after finding the target data according to the data reading request, the Cehp plug-in directly returns the target data to the Hbase client terminal. According to the method and system for data reading, no cache is disposed in a Cehp plug-in layer, which reduces layers of data reading and omits a process of searching for the target data in the cache of the Cehp plug-in layer, and therefore the data reading efficiency is improved compared with the prior art.

Description

technical field [0001] The present application relates to the field of computer processing technology, in particular to a data reading method and system based on the HBase+Hadoop+Ceph docking framework. Background technique [0002] HBase is a distributed, column-oriented open source database. HBase is built on Hadoop's distributed storage system HDFS (Hadoop Distributed File System, distributed file system). It is a column-based database suitable for unstructured data storage. database. [0003] HDFS is a highly fault-tolerant system that can provide high-throughput data access and is very suitable for applications on large-scale data sets. [0004] Hadoop is a distributed system infrastructure developed by the Apache Foundation. Users can develop distributed programs without knowing the underlying details of the distribution, and make full use of the power of the cluster for high-speed computing and storage. The architecture of Hadoop mainly realizes the underlying supp...
