Among them, two-copy redundancy can only tolerate the downtime of one storage node. If one storage node goes down, there is only one copy of the data block in the downtime storage node, and there is a risk of data single point; although three-copy redundancy can tolerate two One storage node is down, but when the design is three-copy redundancy, the storage space of each storage node is greatly reduced, and the effective storage capacity of the storage space is only 1 / 3
[0004] To sum up, the database all-in-one machine in the prior art is difficult to be compatible with the reliability of the data block in the storage node and the effective utilization of the storage space

Embodiments of the invention disclose a data processing device, a database integrated machine and a data processing method. The data processing device is arranged in each backup node of the database integrated machine; and an address and data block information of each storage node is stored in the storage node of the database integrated machine. The data processing device comprises a storage module, a detection module and a processing module, wherein the storage module is used for storing the address of each storage node in the database integrated machine; the detection module is used for detecting the working state of each storage ode; the processing module is used for backing up data blocks in the second storage node into an appointed backup node when the fact that the first storage nodebreaks down is detected by the detection module; and the second storage node is a storage node for storing a part of or all the data blocks in the first storage node. According to the data processingdevice, the database integrated machine and the data processing method, the reliability of the data blocks in the storage nodes can be improved on the basis of ensuring the effective utilization of storage spaces.
Description
technical field [0001] The present application relates to but not limited to the technical fields of computers and databases, especially a data processing device, a database integrated machine and a data processing method thereof. Background technique [0002] With the development of computer and database technology, big data has penetrated into all walks of life and business functions, and has gradually become an indispensable data resource. [0003] Big Data Appliance (abbreviated as: BDA) is a combination of software and hardware designed for the analysis and processing of large amounts of data. It has been widely used for example based on fusion computing, storage, high-speed network and database High-performance database all-in-one machine. The typical configuration of the current database all-in-one machine is, for example: 2 computing nodes + 3 storage nodes, and the data blocks of the storage nodes are generally designed as two-copy redundancy, and can also be desig...
