Creating a schema with SDK for Python (Boto3)

1. Define the Avro format schema that you want to use.

2. Save the schema in a JSON file in the default Python folder.

3. Create the schema using the following code.

   import boto3
   
   personalize = boto3.client('personalize')
   
   with open('schema.json') as f:
       createSchemaResponse = personalize.create_schema(
           name = 'YourSchema'
           schema = f.read()
       )
   
   schema_arn = createSchemaResponse['schemaArn']
   
   print('Schema ARN:' + schema_arn )

4. Amazon Personalize returns the ARN of the new schema. Store it for later use.

Amazon Personalize provides operations for managing schemas. For example, you can use the ListSchemas API to get a list of the available schemas.

After you create a schema, use it with datasets that match the schema. For more information, see Data format guidelines.
