Smart Cities
A city platform collects from traffic, lighting, water, waste and safety systems, each owned by a different department, often with different vendors. The platform must share infrastructure without sharing data by accident.
Workload shape
| Writes | Continuous sensor streams |
|---|---|
| Reads | Dashboards, incident lookups, reports |
| Tenancy | Departments and vendors |
| Sensitivity | Citizen data under clearance |
How the data lands
Design fit, not a customer claim: which parts of UltraFabric carry which parts of this workload.
- One tenant per department, or per vendor contract, on a single cluster
- Counters and sensor events as columnar collections; incidents and assets as rows
- Fields above a user's clearance masked by the verifier, not by application code
What it looks like
A department's token scopes every table it touches; no WHERE clause carries the boundary.
CREATE TABLE junction_counts (id bigint PRIMARY KEY, junction text NOT NULL,
minute timestamp, vehicles int, avg_speed numeric(6,2)) WITH (storage = columnar);
SELECT junction, avg(avg_speed), sum(vehicles)
FROM junction_counts GROUP BY junction ORDER BY 3 DESC LIMIT 20;Built today, coming next
Everything in the first column is in the repository and tested; the second column is the roadmap in order.
Built today
- Clearance-based field masking enforced in the verifier
- Append-only columnar collections with duplicate keys rejected at insert
- Identity derived only from the token the node verified
Next
- Row-level policies compiled on the node
- Vector and text search behind the same verifier
- The managed service after replication and backups
Other use cases
Airports & Aviation
An airport runs many organisations on one estate: the operator, airlines, ground handlers, security and government agencies.
Power & Utilities
Grid operators keep two kinds of data that rarely live well together: dense measurement streams and slow-changing asset records.
Public Sector
Government platforms host many departments on shared infrastructure, each with statutory limits on who may see what.
Manufacturing
A production line emits events that must never be lost or overwritten, alongside quality and supply records that change.
