A real-time data store

Abstract

The invention discloses a real-time data storage device. The real-time data storage device comprises an interface layer, a caching layer, a column-type database layer and a data persistence layer, wherein the interface layer is used for providing a querying interface and a writing-in interface outwards, analyzing a querying order and a writing-in order to be in an internal-appointment data format, then transmitting the result to the caching layer, packaging the querying result and the writing-in result and carrying out responding; the caching layer is used for receiving the querying order and the writing-in order which come from the interface layer, and returning the querying result and the writing-in result to the interface layer; the column-type database layer is used for storing data indexes and data contents; the data persistence layer is used for storing file blocks through a distributed file system. The real-time data storage device has the advantages that the international standard of the field of the Internet of Things is achieved, and main application scenes of the field of the Internet of Things are met; particularly, for storage of a larger amount of sensor data, a single-point fault is avoided, and the reliability is high while the capacity is enormous.

Description

technical field [0001] The invention relates to the technical field of information storage, in particular to a real-time data storage. Background technique [0002] ISO18880 is an international standard in the field of the Internet of Things. It was released in 2015 and is a standard that combines information and communication technology with energy conservation. This standard is based on the key points necessary for data transmission between the perception layer and the network layer of the Internet of Things. Through the standardized processing of multi-protocol information at the sensor nodes of the perception layer, the standardized application of information at the network layer of the Internet of Things is promoted, and the data interface between the network layer and the application layer is standardized. In turn, it can form the core of IoT data aggregation, and can use accurate remote control and operation to provide collaborative management solutions for community ...
