cadre
High-performance, minimal remote configuration service that's extremely simple to set up and use.
Configuration is backed by S3, updated from a human-readable web interface and
persisted to a file on disk. Multiple environments are supported and accessible
from a JSON web API. Plus, cadre is really easy to set up: just run a single
binary that contains the entire application, passing in an S3 bucket name.
The web server is written in Rust and can easily support over 80,000 HTTP/2 requests per second running on a consumer MacBook Pro, tested using vegeta. It's also horizontally scalable.
Template values have keys that are prefixed with the * character. These values
are resolved at request-time.
aws:<NAME>: A secret stored in
AWS Secrets Manager. For
performance, secrets are cached by the server for up to a minute.All resolution of fields within templates is recursive.
This library is created by the team behind Modal for their own use.
