AttributeConfig
Provides information about the method used to transform attributes.
The following is an example using the RETAIL domain:
{
"AttributeName": "demand",
"Transformations": {"aggregation": "sum", "middlefill": "zero", "backfill":
"zero"}
}
Contents
 AttributeName

The name of the attribute as specified in the schema. Amazon Forecast supports the target field of the target time series and the related time series datasets. For example, for the RETAIL domain, the target is
demand
.Type: String
Length Constraints: Minimum length of 1. Maximum length of 63.
Pattern:
^[azAZ][azAZ09_]*
Required: Yes
 Transformations

The method parameters (keyvalue pairs), which are a map of override parameters. Specify these parameters to override the default values. Related Time Series attributes do not accept aggregation parameters.
The following list shows the parameters and their valid values for the "filling" featurization method for a Target Time Series dataset. Default values are bolded.

aggregation
: sum,avg
,first
,min
,max

frontfill
: none 
middlefill
: zero,nan
(not a number),value
,median
,mean
,min
,max

backfill
: zero,nan
,value
,median
,mean
,min
,max
The following list shows the parameters and their valid values for a Related Time Series featurization method (there are no defaults):

middlefill
:zero
,value
,median
,mean
,min
,max

backfill
:zero
,value
,median
,mean
,min
,max

futurefill
:zero
,value
,median
,mean
,min
,max
To set a filling method to a specific value, set the fill parameter to
value
and define the value in a corresponding_value
parameter. For example, to set backfilling to a value of 2, include the following:"backfill": "value"
and"backfill_value":"2"
.Type: String to string map
Map Entries: Maximum number of 20 items.
Key Length Constraints: Minimum length of 1. Maximum length of 63.
Key Pattern:
^[azAZ][azAZ09_]*
Value Length Constraints: Maximum length of 256.
Value Pattern:
^[azAZ09\_\]+$
Required: Yes
