Data hybrid retrieval method, device, equipment and readable storage medium

By retrieving static performance data in relational databases and dynamic performance data in distributed cache databases on demand in the Internet of Things scenario, and calculating the target data based on the retrieval results, the hybrid data retrieval delay in the existing technology is solved. For long problems with low real-time performance, low memory consumption and low latency retrieval effects are achieved.

AI Technical Summary

Technical Problem

When performing mixed data retrieval in the Internet of Things scenario, the time delay is long and the real-time performance is low, especially when dynamic data is stored in a time series database or a document database.

Method used

By obtaining the retrieval expression of the target data to be retrieved, the static performance data in the relational database and the dynamic performance data in the distributed cache database are retrieved on demand, and the target data is calculated based on the retrieval results, reducing memory consumption and delay.

Benefits of technology

The mixed retrieval of low memory consumption and low latency data ensures the real -time nature of retrieval.

Abstract

The present invention provides a data hybrid retrieval method, device, equipment and readable storage medium, which relates to the field of data retrieval. The method includes: obtaining a retrieval expression of target data to be retrieved; searching a relational database according to a first retrieval condition corresponding to the static performance retrieved in the retrieval expression to obtain first data; wherein the relational data stores static performance data of multiple devices; obtaining second data recording dynamic performance in a distributed cache database according to the dynamic performance retrieved in the retrieval expression; wherein the distributed cache database stores dynamic performance data of multiple devices; obtaining target data according to the first data, the second data and the second retrieval condition corresponding to the dynamic performance in the retrieval expression. When using the embodiment of the present invention, the memory consumption is low, the delay is small, and the real-time retrieval is guaranteed.
