FuelPHPでMySQLにインデックスを追加するタスク

Last updated at Posted at 2014-12-25

マイグレーションでも追加できるけど、運用後にインデックスだけメンテナンスしたい場合に不便なので、インデックス関係だけタスクにまとめてしまおうということ。

タスクを作成

ダウンロード(Gist)

fuel/app/tasks/migrate_indexes.php
<?php

namespace Fuel\Tasks;

class Migrate_indexes
{
	
	public static function run()
	{
	}
	
	public static function up()
	{
		static::_up('topics', array('id'), 'idx_id');
		static::_up('topics', array('deleted_at'), 'idx_dl');
		static::_up('topics', array('id','deleted_at'), 'idx_id_dl');
		static::_up('topics', array('deleted_at','created_at'), 'idx_dl_cr');
		static::_up('topics', array('created_at'), 'idx_cr');
		
		static::_up('comments', array('id'), 'idx_id');
		static::_up('comments', array('deleted_at'), 'idx_dl');
		static::_up('comments', array('id','deleted_at'), 'idx_id_dl');
		static::_up('comments', array('deleted_at','created_at'), 'idx_dl_cr');
	}
	
	public static function down()
	{
		static::_down('topics', 'idx_id');
		static::_down('topics', 'idx_dl');
		static::_down('topics', 'idx_id_dl');
		static::_down('topics', 'idx_dl_cr');

		static::_down('comments', 'idx_dl');
		static::_down('comments', 'idx_dl_cr');
		static::_down('comments', 'idx_cr');
	}
	
	protected static function _up($table, $index_columns, $index_name)
	{
		try{
			\DBUtil::create_index($table, $index_columns, $index_name);
			\Cli::write(\Cli::color('Created index: '.$table. ' : '. implode(',',$index_columns). ' : '. $index_name, 'green'));
		}catch( \Fuel\Core\Database_Exception $e ){
		}
	}
	
	protected static function _down($table, $index_name)
	{
		try{
			\DBUtil::drop_index($table, $index_name);
			\Cli::write(\Cli::color('Dropped index: '.$table. ' : '. $index_name, 'green'));
		}catch( \Fuel\Core\Database_Exception $e ){
