Live Config

Watch configuration values change in real time using ConfigWatcher.

What it shows

• client.watch() to create a watcher
• watcher.field() to register typed fields with defaults
• @field.on_change decorator for reactive callbacks
• field.changes() blocking iterator for change events
• field.value for reading the current value at any time

Run

cd examples
make setup
cd live-config
python main.py

Then in another terminal:

decree config set <tenant-id> server.rate_limit 500
