-## Task (`task`)
-
-Task queue configuration has been moved to `queue.task`. However, the below configuration values are kept for backwards compatibility:
-
-- `QUEUE_TYPE`: **channel**: Task queue type, could be `channel` or `redis`.
-- `QUEUE_LENGTH`: **1000**: Task queue length, available only when `QUEUE_TYPE` is `channel`.
-- `QUEUE_CONN_STR`: **redis://127.0.0.1:6379/0**: Task queue connection string, available only when `QUEUE_TYPE` is `redis`. If redis needs a password, use `redis://123@127.0.0.1:6379/0` or `redis+cluster://123@127.0.0.1:6379/0`.
