# This plugin causes database bloating

 * It seems like the checkout fields are stored in the Woo session.
 * ` WC()->session->wooccm['fields']`
 * That represents 95+% of the size of our sessions and is making our database huge.
 * Is there a setting we can enable to change that behavior? To store that on the
   server once instead since 99.84% of them have the exact same value in that field?
 * We reduced the TTL meanwhile, but that’s still heavy writing for large sites 
   with a lot of traffic.
 * Thank you for any assistance! 🙂

 * [@magikweb](https://wordpress.org/support/users/magikweb/) Hi mate,
 * Thanks for your message.
 * WooCommerce sessions are temporary by nature and are automatically cleared over
   time. You can also manually clean them from:
 * WooCommerce → Status → Tools → Clear customer sessions
 * Best regards,
