Forecast has the following service quotas.

Quotas Imposed by the CreateDatasetImportJob API
Resource	Default Quota	Adjustable
Maximum number of files in your Amazon S3 bucket	10,000	No
Maximum cumulative size of all files in your Amazon S3 bucket	30 GB	Yes
Maximum number of datasets in a dataset group	3 (1 for each type)	No
Maximum number of rows in a dataset	3 billion Note: the quota for the ap-south-1 region is 1 billion.	Yes
Maximum number of columns in a target time series dataset (required columns + additional forecast dimensions)	13 (3 + 10)	No
Maximum number of columns in a related time series dataset (required columns + additional forecast dimensions + related features)	25 (2 + 10 + 13)	No
Maximum number of columns in an item metadata dataset	10	No
Maximum number of columns in any other dataset	36	No

Quotas Imposed by the CreatePredictor API
Resource	Default Quota	Adjustable
Maximum `number of backtest windows` (EvaluationParameters)	5	No
Maximum number of time series per predictor (number of items X number of unique values across forecast dimensions in the target time series dataset)	5,000,000 across all target time series items and dimensions. Note: the quota for the ap-south-1 region is 1,000,000 . If you exceed 100,000 items, Forecast supports yearly, monthly, weekly, and daily frequencies instead of more granular frequencies (such as hourly).	Yes
Maximum forecast horizon	CNN-QR, DeepAR+, AutoML: The lesser of 500 data points or 1/3 of the target time series dataset length ETS, NPTS, Prophet, ARIMA: The lesser of 500 data points or the length of the target time series dataset minus one.	No
