This store does not support TTL lower than 1 second.

Before storing locks in the database, you must create the table that stores
the information. The store provides a method called
:method:`Symfony\\Component\\Lock\\Store\\PdoStore::createTable`
to set up this table for you according to the database engine used::

try {
$store->createTable();
} catch (\PDOException $exception) {
// the table could not be created for some reason
}

A great way to set up the table in production is to call the ``createTable()``
method in your local computer and then generate a
:ref:`database migration <doctrine-creating-the-database-tables-schema>`:

.. code-block:: terminal

$ php bin/console doctrine:migrations:diff
$ php bin/console doctrine:migrations:migrate
The table where values are stored is created automatically on the first call to
the :method:`Symfony\\Component\\Lock\\Store\\PdoStore::save` method.
You can also create this table explicitly by calling the
:method:`Symfony\\Component\\Lock\\Store\\PdoStore::createTable` method in
your code.
