-- Retrieves a forecast for a single item, filtered by the supplied
-- criteria.
--
-- The criteria is a key-value pair. The key is either @item_id@ (or the
-- equivalent non-timestamp, non-target field) from the
-- @TARGET_TIME_SERIES@ dataset, or one of the forecast dimensions
-- specified as part of the @FeaturizationConfig@ object.
--
-- By default, @QueryForecast@ returns the complete date range for the
-- filtered forecast. You can request a specific date range.
--
-- To get the full forecast, use the
-- <https://docs.aws.amazon.com/en_us/forecast/latest/dg/API_CreateForecastExportJob.html CreateForecastExportJob>
-- operation.
--
-- The forecasts generated by Amazon Forecast are in the same timezone as
-- the dataset that was used to create the predictor.
