public DatabaseBackend::setMultiple(array $items) Store multiple items in the persistent cache. Parameters array $items: An array of cache items, keyed by cid. In the form: $items = array( $cid => array( // Required, will be automatically serialized if not a string. 'data' => $data, // Optional, defaults to CacheBackendInterface::CACHE_PERMANENT.

public DatabaseBackend::set($cid, $data, $expire = Cache::PERMANENT, array $tags = array()) Stores data in the persistent cache. Core cache implementations set the created time on cache item with microtime(TRUE) rather than REQUEST_TIME_FLOAT, because the created time of cache items should match when they are created, not when the request started. Apart from being more accurate, this increases the chance an item will legitimately be considered valid. Parameters string $cid: The cache ID of the
