Laravel Database Sharring & Table Partitioning

In Laravel, implementing database sharding and partitioning can be achieved through using database migrations and models. Here is a simple example:

1. Create database migration files to establish sharding and partitioning structures.

php artisan make:migration create_users_table --table=db1.users
php artisan make:migration create_posts_table --table=db2.posts

1. Define database table structure in the migration file.

// db1.users migration file
Schema::connection('db1')->create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->timestamps();
});

// db2.posts migration file
Schema::connection('db2')->create('posts', function (Blueprint $table) {
    $table->increments('id');
    $table->string('title');
    $table->text('content');
    $table->timestamps();
});

1. Create a model and specify the database connection to be used.

// User model
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    protected $connection = 'db1';
    protected $table = 'users';
}

// Post model
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $connection = 'db2';
    protected $table = 'posts';
}

1. Performing database operations with models in controllers.

use App\Models\User;
use App\Models\Post;

$users = User::all();
$posts = Post::all();

By following the above steps, we can implement sharding and partitioning in Laravel. In actual projects, more sharding and partitioning structures and models can be defined based on specific requirements.
