Abstract

The invention discloses a data management method for a distributed data storage system. The distributed data storage system comprises a plurality of data servers. The data management method comprises the following steps of: at least acquiring respective load state information and physical position labels of the data servers; receiving a data request from a data requester; at least selecting one of the data servers to process the data request according to the respective load state information and the physical position labels of the data servers, wherein each data server stores requested data corresponding to the data request; reading the requested data from the selected data server; and returning the requested data to the data requester.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data management device and method for a distributed data storage system, and a data management system for a distributed data storage. Background technique [0002] At present, there are many types of databases. The more popular one is the database based on distributed file storage. The so-called distributed file To store data, treat multiple data servers together as a complete database, and jointly complete data writing and reading. Because there are many specific forms of databases, there are also many databases based on distributed file storage. [0003] The following is an example of MongoDB, a commonly used database based on distributed file storage. MongoDB (Data Base, database) is a product between relational databases and non-relational databases. It is the most functional among non-relational databases and most similar to relational databases. Therefore, MongoDB...
