It's almost a new feature but it's still BC.

This is a new feature and it's not compatible with https://github.com/hhamon/symfony/blob/configurable-doctrine-dbal-session-handler/src/Symfony/Bridge/Doctrine/HttpFoundation/DbalSessionHandlerSchema.php

So the schema would need to be configurable as well.

-1 for putting this in 2.3

@stof Shall it be merged into 2.7 instead?

@stof should I close the PR or submit against 2.7?

What is the state here? It must be done in 2.7 and it must also make the schema configurable. In it's current form it's not mergeable. @hhamon are you going to make the changes? Or rather close the PR?

@Tobion I can make the changes in the coming days and submit against 2.7 branch.

But what's the actual advantage of that? I don't really see it. As a session user you don't care how the table looks like.

Should be done in 2.8 or closed. ping @hhamon

Will do ;)

Closing in favor of #14710.
