Cacher

Cacher is a simple in-memory database replication tool developed in Go. It provides methods for managing key-value data in memory, including List, Get, Set, and Delete.

Features

• In-Memory Database: Cacher stores key-value pairs in memory for fast access.
• Expiration: Records inserted into the memory have an expiration date. The software automatically removes expired records from memory at the appropriate time.

Usage

1. Import the Cacher package in your Go code:

import "github.com/cmparrela/go-db-inmemory/cache"

2. Create a new Cacher instance:

cacher := cache.NewCacher()

3. Use the provided methods to manage data:

// Set a key-value pair with an expiration time of 10 minutes
expiration := time.Duration(rand.Intn(10)) * time.Second
cacher.Set("key", "value", expiration)

// Get the value associated with a key
value := cache.Get("key")

// Delete a key-value pair
cache.Delete("key")

// List all key-value pairs in the cache
allData := cache.List()

Example

package main

import (
	"context"
	"github.com/cmparrela/go-db-inmemory/cache"
	"github.com/google/uuid"
	"math/rand"
	"time"
)

func main() {
	ctx := context.Background()
	cacher := cache.NewCacher()

	for i := 1; i < 1000000; i++ {
		expiration := time.Duration(rand.Intn(10)) * time.Second

		key := uuid.New().String()
		cacher.Set(key, "teste", expiration)
	}

	<-ctx.Done()
}
