service-fs
service-fs is the foundational storage layer for the PointSav GIS platform. It implements a data lake model where raw geospatial points ingested from open geospatial sources are stored in a durable, modular file system for downstream analytical processing.
Data Ingestion and Storage
The service maintains a unified filesystem structure with separate landing zones for retail and civic infrastructure data.
- Retail landing: raw commercial operator records ingested from open geospatial registries (OpenStreetMap, Overture Maps Foundation).
- Civic landing: raw civic and institutional facility records from the same open sources.
Architectural Role
As the stateful layer of the platform, service-fs is responsible for data persistence. It is designed to be independent of the analytical software — if the GIS orchestration layer is re-provisioned, the core data assets remain intact within this layer. The clean separation between data persistence and analytical logic is a core design invariant.
Unikernel Implementation
In production, service-fs is deployed as a low-overhead unikernel. It provides a restricted API for the service-business and service-places intelligence layers to read raw data and write back processed results, enforcing clean separation between storage and analysis concerns.
