Zenoh and InfluxDB: Edge ingestion to time-series storage

Zenoh and InfluxDB form a complementary pair for industrial IoT data pipelines. Zenoh handles data collection and transport from edge devices, while InfluxDB provides long-term time-series storage and analytics.

How they work together

Zenoh provides a storage backend that can write data to InfluxDB. This allows Zenoh applications to:

• Collect sensor data via pub/sub from constrained devices
• Store data locally at the edge for resilience
• Forward aggregated data to InfluxDB for long-term retention
• Query historical data through Zenoh's unified query interface

Use cases

• Factory floor sensor aggregation with local buffering
• Telemetry collection from mobile robotics
• Energy monitoring with edge preprocessing
• Condition monitoring with intermittent cloud connectivity

Configuration notes

Zenoh's InfluxDB storage backend requires configuration for:

• InfluxDB endpoint and authentication
• Database and retention policy
• Key mapping from Zenoh paths to InfluxDB measurements
• Batch size and flush intervals

Tradeoffs

• Zenoh adds protocol translation overhead vs direct InfluxDB client
• Benefits include unified query interface and local storage fallback
• Consider direct InfluxDB client for simple, always-connected scenarios
