Create a Ristretto cache, set a key-value pair, and retrieve it.

package main import ( "fmt" "github.com/dgraph-io/ristretto" ) func main() { cache, err := ristretto.NewCache(&ristretto.Config{ NumCounters: 1e7, MaxCost: 1 << 30, BufferItems: 64, }) if err != nil { panic(err) } cache.Set("key", "value", 1) cache.Wait() value, found := cache.Get("key") if found { fmt.Println(value) } }

Debug

Known issues

gotchaRistretto uses a cost-based eviction policy; setting incorrect costs can lead to unexpected evictions.

fix

Ensure the cost parameter in Set() reflects the actual memory usage of the value.
