Sovereign Execution
Sovereign execution allows workflows managed in KNIME Hub to be executed outside the Hub’s own infrastructure, on compute resources that are operated and controlled separately. This enables running workflows closer to the data, within specific network boundaries, or on specialized hardware, while still using KNIME Hub as the central control plane.
Why use Sovereign Execution?
Sovereign execution solves the challenge of "Data Gravity." Instead of moving massive datasets to the KNIME Hub, you move the execution power to the data.
- Data Sovereignty: Process data that must stay local and cannot move into the cloud, while still managing workflows centrally through KNIME Hub.
- Specialized Hardware: Run computationally heavy workflows on dedicated GPU instances or high-memory machines that sit outside the standard Hub cluster.
- Hybrid Cloud Strategy: Keep your KNIME Hub in the cloud while running executors in your on-premise data center.

Installing, updating, and removing sovereign executors
Each task has its own dedicated guide:
- Setting up sovereign executors — enable the feature, configure execution contexts, and install the Executor and Executor Agent
- Updating sovereign executors — update an existing installation to a newer version
- Removing and revoking sovereign executors — decommission an executor or revoke its access
