gomcache

gomcache is a Go library for interacting with Memcached servers using both TCP and UDP protocols. It provides a robust and simple client for performing standard Memcached operations such as setting, getting, deleting cache items, and checking server availability with high-level concurrency support.

Features

• TCP and UDP Support: Choose between TCP or UDP protocols for communication with Memcached servers.
• Simple and Intuitive API: Easy-to-use methods for setting, getting, deleting cache items, and checking server availability with the Ping method.
• High-Level Concurrency: Thread-safe operations with built-in concurrency management for high-performance applications.
• Error Handling: Robust error handling for network and protocol errors, ensuring reliable interactions with Memcached servers.

Installation

To use gomcache in your Go project, you need to install it using go get. Open your terminal and run:

go get github.com/nihankhan/gomcache

Usage

Here's a quick guide on how to use the gomcache library in your Go application:

Import the Package

import "github.com/nihankhan/gomcache"

Create a New Client

Create a new Client instance with the addresses of your Memcached servers:

client, err := gomcache.NewClient([]string{"localhost:11211"}, true) // If false disable UDP or true Enable UDP
if err != nil {
    log.Fatalf("failed to create client: %v", err)
}

Set an Item

Use the Set method to add or update an item in the cache:

item := &gomcache.Item{
    Key:   "foo",
    Value: []byte("bar"),
    Flags: 0,
    Expiration: 3600, // in seconds
}

err := client.Set(item)
if err != nil {
    log.Fatalf("failed to set item: %v", err)
}

Get an Item

Use the Get method to retrieve an item from the cache:

item, err := client.Get("foo")
if err != nil {
    log.Fatalf("failed to get item: %v", err)
}
fmt.Printf("Value: %s\n", item.Value)

Delete an Item

Use the Delete method to remove an item from the cache:

err := client.Delete("foo")
if err != nil {
    log.Fatalf("failed to delete item: %v", err)
}

Ping the Server

Use the Ping method to check if the server is responsive:

err := client.Ping("version\r\n")
if err != nil {
    log.Fatalf("server is not responding: %v", err)
} else {
    fmt.Println("Server is responsive")
}

Testing

To run tests for gomcache, use the go test command:

go test -v ./...
