What it is and what it does
Lance-namespace is a plugin registry and abstract interface layer for Lance namespace implementations. It defines the LanceNamespace ABC that custom storage backends must implement, and provides a connect() factory function to instantiate namespace instances by type. The package re-exports model types from its runtime dependency lance-namespace-urllib3-client, making it a bridge between the Lance ecosystem and pluggable storage backends.
Typical use involves either connecting to built-in implementations (dir for local filesystem, rest for remote HTTP) or registering and connecting to custom implementations. Developers building Lance integrations with external systems would subclass LanceNamespace and register their implementation via register_namespace_impl(), allowing other code to discover and instantiate it by name.
Use it for
- Connect to local or remote Lance storage backends using the factory pattern without coupling to specific implementations.
- Register custom namespace implementations for proprietary or specialized storage systems to integrate with Lance.
- Build a plugin ecosystem where third-party packages can provide Lance namespace adapters without modifying core code.
- Abstract storage backend selection in applications that need to support multiple Lance data sources at runtime.
