-`finish`: Specifies the end value of the batch counting, by default is `relation.maximum(:id)`.
-`cache_start_and_finish_as`: Specifies the cache key for `start` and `finish` values, this is needed only if `start` and `finish` are used.
-`cache_start_and_finish_as`: Specifies the cache key for `start` and `finish` values and sets up caching them. Use this call when `start` and `finish` are expensive queries that should be reused between different metric calculations.
