# Quick Start for Integrators¶

This section gives some simple instructions for getting started using the caching framework without giving the whole details under the hood.

## Change Specific Cache Options¶

By default, most Core caches use the database backend. Default cache configuration is defined in typo3/sysext/core/Configuration/DefaultConfiguration.php and can be overridden in LocalConfiguration.php.

If specific settings should be applied to the configuration, they should be added to LocalConfiguration.php. All settings in LocalConfiguration.php will be merged with DefaultConfiguration.php. The easiest way to see the final cache configuration is to use the TYPO3 backend module SYSTEM > Configuration > \$GLOBALS[‘TYPO3_CONF_VARS’] (with installed lowlevel system extension).

Example for a configuration of redis cache backend on redis database number 42 instead of the default database backend with compression for the pages cache:

return [
// ...
'SYS' => [
// ...
'caching' => [
// ...
'pages' => [
'backend' => \TYPO3\CMS\Core\Cache\Backend\RedisBackend::class,
'options' => [
'database' => 42,
],
],
],
],
];
