CustomIndexBundle

The CustomIndexBundle allows create index for doctrine entities using annotation with entity definition and console command.

Installation

CustomIndexBundle requires Symfony 2.1 or higher. Now work only with PostgreSQL.

Require the bundle in your composer.json file:

{
    "require": {
        "intaro/custom-index-bundle": "~0.1.1",
    }
}

Install the bundle:

$ composer update intaro/custom-index-bundle

Register the bundle in AppKernel:

// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        //...

        new Intaro\CustomIndexBundle\IntaroCustomIndexBundle(),
    );

    //...
}

Usage

1) Add annotation in your entity

<?php

namespace Acme\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Intaro\CustomIndexBundle\Annotations as CustomIndexAnnotation

/**
 * @ORM\Table(name="my_entity")
 * @ORM\Entity()
 * @CustomIndexAnnotation\CustomIndexes(indexes={
 *     @CustomIndexAnnotation\CustomIndex(columns="my_property1"),
 *     @CustomIndexAnnotation\CustomIndex(columns={"lower(my_property1)", "lower(my_property2)"})
 * })
 */
class MyEntity
{
    /**
     * @ORM\Column(type="string", length=256)
     */
    protected $myProperty1;

    /**
     * @ORM\Column(type="string", length=256)
     */
    protected $myProperty2;
}

Available CustomIndex attributes:

  • columns - array of the table columns
  • name - index name (default = 'i_cindex_<md5 hash from all CustomIndex attributes>').
  • unique - index is unique (default = false).
  • using - corresponds to USING directive in PostgreSQL CREATE INDEX command.
  • where - corresponds to WHERE directive in PostgreSQL CREATE INDEX command.

Required only columns attribute.

2) Use intaro:doctrine:index:update command for update db.

php app/console intaro:doctrine:index:update

You may use dump-sql parameter for dump sql with DROP/CRATE INDEX commands

php app/console intaro:doctrine:index:update --dump-sql

Some annotation examples

Create index using pg_trgm extension:

@CustomIndexAnnotation\CustomIndex(columns="lower(my_column) gist_trgm_ops", using="gist")

Create unique index using PostgreSQL functions:

@CustomIndexAnnotation\CustomIndex(columns={"lower(my_column1)", "nullif(true, not my_column2 isnull)"}, unique=true)

Create partial index:

@CustomIndexAnnotation\CustomIndex(columns={"site_id"}, where="product_id IS NULL")
