intaro/custom-index-bundle

Annotation and command for control entity custom indexes

CustomIndexBundle

The CustomIndexBundle allows create index for doctrine entities using attribute with entity definition and console command., _(*1)

Installation

CustomIndexBundle requires Symfony 5 or higher. Works only with PostgreSQL., _(*2)

Run into your project directory:, _(*3)

$ composer require intaro/custom-index-bundle

Register the bundle in config/bundles.php:, _(*4)

<?php

return [
   ...
    Intaro\CustomIndexBundle\IntaroCustomIndexBundle::class => ['all' => true],
];

If your project have many schemas in single database and command must generate custom indexes only for one schema then add in your config.yml:, _(*5)

intaro_custom_index:
    search_in_all_schemas: false
    allowed_index_types: ['gin', 'gist', 'btree', 'hash']

Default value of search_in_all_schemas is true. If you have different entities in different schemas and you need to update custom indexes in all schemas at once then you must set search_in_all_schemas to true or omit this config. If you have database with only public schema then search_in_all_schemas value doesn't matter., _(*6)

Parameter allowed_index_types helps to exclude some types of indexes. If someone will try to use excluded type, command intaro:doctrine:index:update will return an error.
Default value is ['gin', 'gist', 'btree', 'hash']., _(*7)

Usage

1) Add attributes in your entity, _(*8)

<?php

namespace Acme\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Intaro\CustomIndexBundle\Metadata\Attribute\CustomIndex;

#[ORM\Table(name:'my_entity')]
#[ORM\Entity]
#[CustomIndex(columns: ['my_property1'])]
#[CustomIndex(columns: ['lower(my_property1)', 'lower(my_property2)'])]
class MyEntity
{
    #[ORM\Column(type:'string', length: 256)]
    private $myProperty1;
    #[ORM\Column(type:'string', length: 256)]
    private $myProperty2;
}

Available CustomIndex properties:, _(*9)

• 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.

php app/console intaro:doctrine:index:update

You may use dump-sql parameter for dump sql with DROP/CREATE INDEX commands, _(*12)

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

<?php

#[CustomIndex(columns: ['lower(my_column) gist_trgm_ops'], using: 'gist')]

#[CustomIndex(columns: ['lower(my_column1)', 'nullif(true, not my_column2 isnull)'], unique: true)]
