Chain Cache Example

Demonstrates ChainCache[T] — multi-layer caching with automatic backfill.

What it shows

• Building a two-layer cache: L1 (small, fast) + L2 (larger, slower)
• Set writes to all layers simultaneously
• Get tries L1 first; on miss it falls through to L2 and backfills L1 asynchronously
• Delete removes from all layers
• GetLayers() to inspect the layer stack

Production pattern

Replace the L2 in-memory store with a Redis store:

redisClient, _ := rueidis.NewClient(rueidis.ClientOption{
    InitAddress: []string{"localhost:6379"},
})
redisStore, _ := redis.New(redis.Config{Client: redisClient})
l2 := cache.New[Session](redisStore, cache.WithTTL(10*time.Minute))

Run

go run ./examples/chain/
