Please describe.**\r\nI tried to lower the length of the ActionView _deque but could not find a way that would not result in a bug\r\n\r\n\r\n**Describe the solution you'd like**\r\n\r\nI would like to have a method to specify the ActionView queue length, ideally at the subclass definition level.\r\n\r\n**Describe alternatives you've considered**\r\nI tried:\r\n1. Changing the class attribute\r\n\r\n```python\r\nclass MyAction(ActionView):\r\n    args = {\r\n        \"averages\": fields.Integer(\r\n            missing=20,\r\n            example=20,\r\n            description=\"Number of images to average over\",\r\n        )\r\n    }\r\n    # Marshal the response as a string representation of the array\r\n    schema = fields.String()\r\n    _deque = Deque(maxlen=10)\r\n    ...\r\n```\r\nI believe this is rendered useless by the `__init_subclass__` method.\r\n\r\n\r\n2. Overwritting the `_deque` at init:\r\n\r\n```python\r\nclass MyAction(ActionView):\r\n    args = {\r\n        \"averages\": fields.Integer(\r\n            missing=20,\r\n            example=20,\r\n            description=\"Number of images to average over\",\r\n        )\r\n    }\r\n    # Marshal the response as a string representation of the array\r\n    schema = fields.String()\r\n    def __init__(self, *args, **kwargs):\r\n        super().__init__(*args, **kwargs)\r\n        self._deque = Deque(maxlen=10)\r\n    ...\r\n```\r\nThis solution is causing the request to hang.\r\n\r\n\r\nI also tried subclassing `__init_subclass__` (?) but to no avail.\r\n\r\nThanks again for your work, sorry for the spam today :)","author":{"url":"https://github.com/glyg","@type":"Person","name":"glyg"},"datePublished":"2021-11-26T15:06:19.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/300/python-labthings/issues/300"}
