Learn more about ProvisionedThroughput on AWS API documentation. ProvisionedThroughput is the maximun read and write capacity that an application can consume on a table. Take note of the AttributeType and ProvisionedThroughput. Only the partition key and the sort key are required. In the script, we will be defining the structure of the table. We are also connecting to DynamoDB local server. Import the dependency in every script connecting to DynamoDB. In the script above, the first thing is to import the boto3 dependency. # Print tablle status print( 'Status:', device_table. 'WriteCapacityUnits': 10 # WriteCapacityUnits set to 10 writes per second # ReadCapacityUnits set to 10 strongly consistent reads per second 'ReadCapacityUnits': 10, 'S' is string type and 'N' is number type 'AttributeType': 'S' 'dynamodb', endpoint_url = ' # Table defination Import boto3 # import Boto3 def create_devices_table(dynamodb =None):
