Provider

The provider concept abstracts the source objects and ability to fetch them and iterate over them. It is useful in combination with persister to populate the index with the data.

Note: The doc describes v5 api which is disabled by default.

Here's example on how to configure Doctrine ORM provider

# app/config/config.yml

fos_elastica:
    indexes:
        theIndexName:
            persistence:
                driver: orm
                model: Application\UserBundle\Entity\User
                provider: ~
