Abstract

The invention provides a distributed relational database based on an HDFS metadata server and a construction method, belonging to the field of distributed databases. The construction method partitions the data according to the coverage of the HDFS system, and stores the data in the regional HDFS according to the partition; the regional HDFS generates metadata according to the stored resource data, and sends the metadata to the corresponding child nodes; and The child node corresponding to the area HDFS stores the metadata, generates a unique identifier according to the metadata, and sends the metadata and the unique identifier to the HDFS metadata server; the metadata server stores the unique identifier, and Metadata and unique identifier are sent to the root node, and a user interface is set, through which layer-by-layer feedback of user requests is performed in the database. The invention establishes the relationship between the parent node and the child node through the metadata server, and realizes the distributed relational data storage of cross-region and multi-branch data sources.

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 foundation of the overall architecture, which not only needs to effectively organize massive data, but also provides efficient interfaces to the upper-level 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 index functions. 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 inexpensive machines and has a high degree of compatibility. When HDFS is applied to the base layer of a specifi...
