TYPO3 Core

I would suggest to rather create a global var:

$GLOBALS['TCA'] = GeneralUtility::makeInstance('TYPO3\CMS\Core\WHATEVER\DatabaseBackedArray');

and create the appropriate class like

class DatabaseBackedArray implements arrayaccess {

according to the PHP docs:
http://php.net/manual/en/class.arrayaccess.php

Then it would be possible to load required parts of TYPO3_CONF_VARS and/or TCA just on requirement from the DB (or eventually store it in a memcached, etc. Cache backend)

Hello Bernhard,

we already thought of that, but it should be discussed in an own issue. It has nothing to do with the bare switch of the caching technique and is a discussion about the general handling of the TCA. Please open a new issue and remove your -1 on the patch.
