Kuiper has released Kuiper 0.5.0

Kuiper 0.5.0 can be downloaded here.

EMQ X Kuiper is a lightweight open source software for Internet of Things edge analysis and streaming processing implemented by Golang, which can run on all kinds of edge devices with limited resources. One of the main goals of Kuiper’s design is to move real-time streaming computing frameworks (such as Apache Spark, Apache Storm, and Apache Flink) running in the cloud to the edge. Kuiper refers to the architecture and implementation of the cloud streaming processing project mentioned above, combines the characteristics of edge streaming data processing, and adopts the rule engine based on Source, SQL (business logic processing) and target (Sink) to realize edge streaming data processing.

Application scenarios of Kuiper include: operating in various edge scenarios of the Internet of Things, such as real-time processing of production line data in the Industrial Internet of Things; Real-time analysis of vehicle-to-vehicle data from the vehicle bus in the Internet of Vehicles; In smart city scenarios, real-time analysis of data from various urban facilities. Through the processing of Kuiper at the edge, the system response speed can be improved, the cost of network bandwidth and storage can be saved, and the security of the system can be improved.
