eKuiper is an edge lightweight IoT data analytics / streaming software implemented by Golang, and it can be run on all kinds of resource-constrained edge devices. It migrates cloud real-time cloud streaming analytics frameworks such as Apache Spark, Apache Storm and Apache Flink to the edge. eKuiper references these cloud streaming frameworks, and also considers any special requirements of edge analytics, to introduce  rule engine, which is based on Source, SQL (business logic) and Sink;  rule engine is used for developing streaming applications at the edge.

User scenarios

It can be run at various IoT edge use scenarios:

 Real-time processing of production line data in the IIoT

 Gateway of Connected Vehicle analyze the data from data-bus in real time

Real-time analysis of urban facility data in smart city scenarios

eKuiper processing at the edge can reduce system response latency, save network bandwidth and storage costs, and improve system security.
