# felu

WIP, ignore for now.

## Crates
### bin
* [felu-mgmt](./felu-mgmt/README.md)
* [felu-ns](./felu-ns/README.md)

### lib
* [felu-common](./felu-common/README.md)

## Initial notes:
### Communication
Certs!

Protobufs over gRPC or just TCP?
Which is easier when we need a stream?

One-way stream? Mgmt sends data to ns, and ns can respond Results to received
messages, but not send messages to mgmt.

### Version control
Configuration version number.
Whole config hash?

### Health checks
Check if all available and on correct version of config.
Send config update if not.

5 second intervals.

### Atomic updates
Swap config after update in one operation.

## Scenarios
### New felu-ns
Receive whole config.

### Config updated
Existing felu-ns receive update.

#### felu-ns network flaky just as config was supposed to come
Health check will re-send if this happens.
