How to Persist Zenoh Data

If you're running Zenoh, whether as rmw_zenoh in ROS 2 or as the transport between a robot, a gateway, and the cloud, you'll eventually run into the same question:

"Where does this data actually go? I need to replay yesterday's run, debug a fault from a remote robot, and pull a few thousand frames for training."

There's plenty of material on the communication layer itself: pub/sub primitives, how Zenoh compares to DDS, multi-node setups down to a Raspberry Pi. rmw_zenoh reached Tier-1 status starting with ROS 2 Kilted Kaiju, and it's getting real attention at events like ROSCon.

What's harder to find is the next layer: what happens to a sample after it's published. Connecting a live Zenoh network to something persistent and queryable usually means working around the limits of Zenoh's existing storage options.

This post shows another way. By the end you'll have a Python publisher sending data over Zenoh, a storage backend persisting it automatically, and a query client pulling exact time ranges back out, all without a custom backend or a bridge process.

CRA-Compliant Robotics Data Storage 2026: How to Solve the Data Storage Challenges of the CRA

The CRA Deadline Every German Robot Operator Must Face

The EU Cyber Resilience Act (Regulation (EU) 2024/2847) is the “GDPR for connected products.” It entered into force on 10 December 2024, with critical milestones approaching fast:

  • 11 September 2026: Mandatory reporting of actively exploited vulnerabilities and severe incidents (24-hour early warning, 72-hour full notification).
  • 11 December 2027: Full compliance — Security by Design, lifecycle support (minimum 5 years), technical documentation, and CE marking.

For robotics fleets (AMRs, cobots, autonomous systems, and ROS 2-based platforms) the stakes are particularly high. These systems are “products with digital elements” (often Class II or critical), generating massive multimodal data streams (camera feeds, LiDAR, IMU, logs, ROS bags) under real production constraints: intermittent connectivity, edge hardware limits, and high physical safety risks.

Generic storage solutions force painful trade-offs: either accept data loss and compliance gaps, or accept exploding costs and slow performance. ReductStore eliminates this trade-off.

Introduction Diagram

Robots generate massive amounts of data, and managing it well is harder than it looks. Storage fills up fast, cloud transfer gets expensive, and real time ingestion is unforgiving when you're running cameras and sensors at high frequency.

This article covers practical strategies for handling robotic data, introduces ReductStore, and walks through a hands on example. Along the way, we cover native ROS integration, Grafana dashboards, MCAP export for Foxglove, a Zenoh API, and native S3 and Azure backends. We also compare ReductStore against Rosbag and MongoDB so you can pick the right tool for each part of your stack.
