LF Edge eKuiper - Lightweight data stream processing engine for IoT edge

LF Edge eKuiper is a lightweight IoT data analytics and stream processing engine running on resource-constraint edge devices. The major goal for eKuiper is to provide a streaming software framework (similar to Apache Flink) in edge side. eKuiper's rule engine allows user to provide either SQL-based or graph based (similar to Node-RED) rules to create IoT edge analytics applications within few minutes.
