Problems with variables

• Cumbersome to mana!e environment specific confi!uration

• Loaded on every request

So we killed it!- No more variable_trololoo()

- No more Features?

Content vs confi!uration

• Can you !ive it a default value?

• Would it benefit si!nifically from direct sql-queries?

• Is it environment specific?

How does it work?

• Object oriented approach:

• BEFORE: variable_set(‘my variable’, $data);

• NOW: $confi!->set(‘my variable’, $data)->save();

How does it work?• Confi!uration locations:

• sites/default/files/confi!_{hash}/active

• sites/default/files/confi!_{hash}/sta!in!

• Confi!uration files:

• manifest.ima!e.styles.yml

• ima!e.settin!s.yml

• ima!e.style.medium.yml
