easyKV is based on the backends of confd. easyKV provides a very simple interface to work with some key-value stores. The goal of easyKV is to abstract these 2 common operations for multiple backends:
- recursively query the kv-store for key-value pairs.
- watch a key-prefix for changes.
A storage backend in easyKV should implement (fully or partially) this interface:
type ReadWatcher interface {
GetValues(keys []string) (map[string]string, error)
WatchPrefix(ctx context.Context, prefix string, opts ...WatchOption) (uint64, error)
Close()
