ForecastQueryService / Client / query_forecast

query_forecast#

ForecastQueryService.Client.query_forecast(**kwargs)#

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 CreateForecastExportJob operation.

Note

The forecasts generated by Amazon Forecast are in the same timezone as the dataset that was used to create the predictor.
