-- `storage_type`: The storage type for the experience buffer.
-  - `queue`: Experience data is stored in a queue. This storage type is recommended for most use cases.
-  - `sql`: Experience data is stored in a SQL database. If your database only supports local access (e.g., SQLite), set `wrap_in_ray` to `True` to wrap the database in a Ray actor, enabling remote access from other nodes.
-  - `file`: Experience data is stored in a JSON file. This storage type should be used only for debugging purposes in `explore` mode.

-- `use_priority_queue`: Only take effect when `storage_type` is `queue`. If set to `True`, the queue will be a priority queue, which allows for prioritizing certain experiences over others. Default is `False`.
-- `reuse_cooldown_time`: Only take effect when `storage_type` is `queue` and `use_priority_queue` is `True`. If set, it specifies the cooldown time (in seconds) for reusing experiences. If not specified, the default value is `None`, meaning experiences can not be reused.
