Redis

Redis keys, with native watch via keyspace notifications.

Install

go get github.com/xavidop/mamori/providers/redis

import _ "github.com/xavidop/mamori/providers/redis"

Using the ref

A redis:// ref points at one Redis key, fetched with a single GET.

redis://<key>[#json-key]

Examples

• redis://app/flags reads the key app/flags and returns its raw string value.
• redis://app/settings#timeout_ms treats the key app/settings as JSON and returns its timeout_ms field - pair it with an int field.
• redis://config/app/db#password selects the password field from a JSON value stored at config/app/db.

type Config struct {
	FeatureFlags string `source:"redis://app/flags"`
	Timeout      int    `source:"redis://app/settings#timeout_ms"` // key holds JSON
}

Value.Version is a content hash of the stored value - Redis has no per-key revision counter - so mamori still gets cheap change detection. Redis usually holds configuration and caches rather than managed secrets, so values are not marked sensitive; wrap a field in secret.String if you want redaction anyway.

Watch

Watch subscribes to Redis keyspace notifications and re-reads the key on change. This requires the server to have notifications enabled:

redis-cli config set notify-keyspace-events KEA

Set the database index with WithDB(n) if your key lives outside DB 0. Without keyspace notifications, use polling (WithPollInterval).

Configuration

import redisprov "github.com/xavidop/mamori/providers/redis"

mamori.WithProvider(redisprov.New(redisprov.WithAddr("redis:6379"), redisprov.WithDB(0)))

Verified with an in-memory fake; live behavior against a real Redis is covered by //go:build integration tests.
