reference-data-loader-add

To load static reference data into a .NET Docker image at startup, implement a loader class that reads bundled datasets and registers them via dependency injection in Program.cs for fast in-memory lookups.

Bundling read-only datasets in a C# application is best achieved by packing static files into the Docker image and loading them into memory at startup, ensuring deterministic access without external database dependencies.

You can avoid race conditions when reloading reference data in a dotnet service by using atomic FrozenDictionary swaps, which safely replace the backing data structure without locking read operations.

The FlightJar reference-data loader supports async operations by satisfying the loader interface with LoadFromAsync and LoadFirstAvailableAsync methods, allowing non-blocking startup data initialization.

To add a new reference-data file to a Docker container, drop the dataset into the /data directory and restart the service; the frozen dictionary loader automatically reads and loads it at startup.
