ForecastQueryService.
Client
¶A low-level client representing Amazon Forecast Query Service
Provides APIs for creating and managing Amazon Forecast resources.
client = session.create_client('forecastquery')
These are the available methods:
can_paginate
(operation_name)¶Check if an operation can be paginated.
create_foo
, and you'd normally invoke the
operation as client.create_foo(**kwargs)
, if the
create_foo
operation can be paginated, you can use the
call client.get_paginator("create_foo")
.True
if the operation can be paginated,
False
otherwise.close
()¶Closes underlying endpoint connections.
get_paginator
(operation_name)¶Create a paginator for an operation.
create_foo
, and you'd normally invoke the
operation as client.create_foo(**kwargs)
, if the
create_foo
operation can be paginated, you can use the
call client.get_paginator("create_foo")
.client.can_paginate
method to
check if an operation is pageable.get_waiter
(waiter_name)¶Returns an object that can wait for some condition.
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.

Request Syntax
response = client.query_forecast(
ForecastArn='string',
StartDate='string',
EndDate='string',
Filters={
'string': 'string'
},
NextToken='string'
)
[REQUIRED]
The Amazon Resource Name (ARN) of the forecast to query.
[REQUIRED]
The filtering criteria to apply when retrieving the forecast. For example, to get the forecast for client_21
in the electricity usage dataset, specify the following:
{"item_id" : "client_21"}
To get the full forecast, use the CreateForecastExportJob operation.
NextToken
. To retrieve the next set of results, use the token in the next request. Tokens expire after 24 hours.dict
