+- `LENGTH`: **100**: Maximal queue size before channel queues block
 - `BATCH_LENGTH`: **20**: Batch data before passing to the handler
-- `CONN_STR`: **redis://127.0.0.1:6379/0**: Connection string for the redis queue type. Options can be set using query params. Similarly LevelDB options can also be set using: **leveldb://relative/path?option=value** or **leveldb:///absolute/path?option=value**, and will override `DATADIR`
+- `CONN_STR`: **redis://127.0.0.1:6379/0**: Connection string for the redis queue type. Options can be set using query params. Similarly, LevelDB options can also be set using: **leveldb://relative/path?option=value** or **leveldb:///absolute/path?option=value**, and will override `DATADIR`
 - `QUEUE_NAME`: **_queue**: The suffix for default redis and disk queue name. Individual queues will default to **`name`**`QUEUE_NAME` but can be overridden in the specific `queue.name` section.
-- `SET_NAME`: **_unique**: The suffix that will be added to the default redis and disk queue `set` name for unique queues. Individual queues will default to
- **`name`**`QUEUE_NAME`_`SET_NAME`_ but can be overridden in the specific `queue.name` section.
-- `WRAP_IF_NECESSARY`: **true**: Will wrap queues with a timeoutable queue if the selected queue is not ready to be created - (Only relevant for the level queue.)
-- `MAX_ATTEMPTS`: **10**: Maximum number of attempts to create the wrapped queue
-- `TIMEOUT`: **GRACEFUL_HAMMER_TIME + 30s**: Timeout the creation of the wrapped queue if it takes longer than this to create.
-- Queues by default come with a dynamically scaling worker pool. The following settings configure this:
-- `WORKERS`: **0**: Number of initial workers for the queue.
+- `SET_NAME`: **_unique**: The suffix that will be added to the default redis and disk queue `set` name for unique queues. Individual queues will default to **`name`**`QUEUE_NAME`_`SET_NAME`_ but can be overridden in the specific `queue.name` section.
 - `MAX_WORKERS`: **10**: Maximum number of worker go-routines for the queue.
-- `BLOCK_TIMEOUT`: **1s**: If the queue blocks for this time, boost the number of workers - the `BLOCK_TIMEOUT` will then be doubled before boosting again whilst the boost is ongoing.
-- `BOOST_TIMEOUT`: **5m**: Boost workers will timeout after this long.
-- `BOOST_WORKERS`: **1**: This many workers will be added to the worker pool if there is a boost.
