$key_prefix_flush_method

method to flush the keys when key_prefix is used.

protected mixed $key_prefix_flush_method = 'direct'

direct: uses SCAN and DEL, but it can take huge time jkvdbredisworker: it stores the keys prefix to delete into a redis list named 'jkvdbredisdelkeys'. You can use a script to launch a worker which pops from this list prefix of keys to delete, and delete them with SCAN/DEL redis commands. See the redisworker controller in the jelix module. event: send a jEvent. It's up to your application to respond to this event and to implement your prefered method to delete all keys.
