Abstract

The invention provides a distributed relational database based on an HDFS metadata server and a construction method, and belongs to the field of distributed databases. The construction method comprises the following steps: partitioning data according to the coverage range of an HDFS system, and storing the data in a regional HDFS according to partitions; adopting the regional HDFS to generate metadata according to the stored resource data and send the metadata to the corresponding child nodes; adopting the sub-nodes corresponding to the regional HDFS to store the metadata, generate unique identifiers according to the metadata, and send the metadata and the unique identifiers to an HDFS metadata server; and adopting the metadata server to store the unique identifier, send the metadata and the unique identifier to the root node, sets a user interface, and feed back a user request layer by layer in a database through the user interface. According to the invention, the relationship betweenthe father node and the child node is established through the metadata server, so that cross-region and multi-branch data source distributed relationship data storage is realized.

Description

technical field [0001] The invention belongs to the field of distributed databases, and in particular relates to a distributed relational database based on an HDFS metadata server and a construction method. Background technique [0002] In the Internet platform architecture, the data storage layer is the basis of the overall architecture. It not only needs to effectively organize massive data, but also provides an efficient interface to the upper database system to meet the needs of massive structured data analysis. For example, for a mature cloud storage system, its database system must have a stable architecture, good scalability, compatibility, and friendly query and indexing functions. Hadoop Distributed File System (Hadoop Distributed File System, HDFS) is a distributed file system that runs on general-purpose hardware and is highly fault-tolerant. It is suitable for deployment on cheap machines and has a high degree of compatibility. When HDFS is applied to the specif...
