Abstract

The invention discloses a data query method and device. The method comprises: acquiring a first query request, the first query request comprising at least one first attribute name and at least one first attribute value, and the first attribute names corresponding to the first attribute values in a one-to-one mode; determining a first target rule set according to the first query request; traversingeach rule in the first target rule set, and searching a first target rule associated with the first attribute value; querying a corresponding first target device identifier based on the first targetrule; obtaining a first query result from a first target device corresponding to the first target device identifier; and determining a target result according to the first query result. According to the method and the device, the technical problem of relatively low large-scale data query efficiency by utilizing a MapReduce framework in the prior art is solved.

Description

technical field [0001] The present application relates to the field of computers, in particular, to a data query method and device. Background technique [0002] With the continuous development of the Internet, the data we can collect and obtain has exploded, and the scale of data has continued to increase. Although the data collection and storage technology is still improving and becoming more mature, how to quickly query and obtain such a huge amount of data has become a new problem. In traditional stand-alone databases, indexing is usually used to improve data query efficiency. However, with the continuous increase of data scale and the gradual complexity and diversification of query statements, traditional database query methods have been difficult to meet Query requirements for large-scale data. [0003] MapReduce is a distributed architecture model for parallel processing of large-scale data. The MapReduce model draws on the built-in functions Map and Reduce in the ...
