Use Cases and Solutions

rekuiper performs real-time stream computation on resource-constrained edge hardware. This section describes production architectures and streaming SQL implementations across key industrial and IoT domains.

Industry Solutions

• Industrial IoT (IIoT): Filter sensor noise, calculate moving averages, detect equipment anomalies, and execute local control loops on industrial PCs and factory edge gateways.
• Connected Vehicles and EV Charging: Ingest high-frequency CAN bus telemetry, process dynamic EV charging sessions using SESSIONWINDOW, and downsample telematics for cellular bandwidth optimization.
• ESPHome Fleet Telemetry: Route and aggregate thousands of microcontroller sensor streams using meta(topic) dynamic routing with sub-5MB memory footprints.
• Public Data Analysis: Process, aggregate, and transform open data feeds using HTTP pull sources and temporal SQL windows.
