Go-Cache

Go-Cache is a hybrid caching library that uses both in-memory and Redis for caching. It provides a simple interface to set, get, and delete cache entries.

Features

• In-memory caching using Ristretto
• Redis caching
• Set and get cache entries
• Delete cache entries
• Delete multiple keys by pattern
• Generate cache keys using SHA256

Installation

To install Go-Cache, use go get:

go get github.com/xplore-run/go-cache

Test

export REDIS_HOST="localhost:6379"
export REDIS_PASSWORD="yhft67egjdkd"

Usage

Initialize HybridCache

import (
    "github.com/yourusername/go-cache"
    "github.com/redis/go-redis/v9"
    "time"
)

func main() {
    redisClient := redis.NewClient(&redis.Options{
        Addr: "localhost:6379",
    })

    cache := cache.NewHybridCache(cache.HybridCacheOption{
        ExpiresInMemory: 5 * time.Minute,
        ExpiresRedis:    10 * time.Minute,
        Prefix:          "myapp",
        Redis:           redisClient,
        MaxCost:         1000,
    })
}

Set and Get Cache Entries

cache.Set("key", []byte("value"))

value, found := cache.Get("key")
if found {
    fmt.Println("Cache hit:", string(value))
} else {
    fmt.Println("Cache miss")
}

Delete Cache Entries

cache.Del("key")

Delete Multiple Keys by Pattern

err := cache.DeleteKeysByPatternFromRedis(context.Background(), "myapp:*")
if err != nil {
    log.Fatalf("Error deleting keys: %v", err)
}

Generate Cache Key

cacheKey := cache.GetCacheKey("some data")
fmt.Println("Generated cache key:", cacheKey)

Close Cache

cache.Close()
