ORM Lite Bundle

===============

[Doctrine](http://www.doctrine-project.org/projects/orm.html) is great for managing relatively small numbers of objects.

But when you need to handle large datasets (e.g. > 10,000 objects), the increased memory usage and slow queries start to

become a problem.

This bundle lets you continue to use some of Doctrine's features with minimal overhead.

### Stuff that works

- Mappings and schema management

- Migrations and fixtures

- Queries with simple criteria such as `array('userId' => 1)`

- Bulk INSERT, UPDATE and DELETE

- Entities with public properties

### Stuff that doesn't work

- Entities with private or protected properties

- Associations and lazy loading

- Tracking object state and flushing changes

- Compound primary keys

- Custom repository classes

- Probably a lot more

Installation

------------

1. Require in `composer.json`: `"outlandish/orm-lite-bundle": "dev-master"`

2. Activate in `AppKernel.php`: `new \Outlandish\OrmLiteBundle\OrmLiteBundle(),`

3. Import into `config.yml`: `resource: @OrmLiteBundle/Resources/config/services.yml`

Usage Example

-------------

Point.php

    /** @Entity */

    class Point {

        /** @Id @Column(type="integer") @GeneratedValue */

        public $id;

        /** @Column(type="integer") */

        public $x;

        /** @Column(type="integer") */

        public $y;

    }

PointController.php

    class PointController extends ContainerAware {

        public function exampleAction() {

            //get entity manager from service container

            $ormLite = $this->container->get('outlandish.ormlite');

            //get array of objects of class 'Point' where x=0

            $points = $ormLite->findBy('Point', array('x' => 0));

            //modify objects

            foreach ($points as $point) {

                $point->x = 1;

            }

            //persist them

            $ormLite->update($points);

            //create some new objects

            $newPoints = array();

            for ($i=0; $i < 10000; $i++) {

                $point = new Point();

                $point->x = random(-50, 50);

                $point->y = random(-10, 10);

                $newPoints[] = $point;

            }

            //persist them

            $ormLite->insert($newPoints);

        }

    }
