Your company currently is maintaining excel sheets with data that now needs to be ported to a DynamoDB table. The excel sheet contains the following headers for the data.
· Customer ID
· Customer Name
· Customer Location
· Customer Age
Which of the following would be the ideal partition key for the data table in DynamoDB?

Answer options:

A.Customer ID
B.Customer Name
C.Customer Location
D.Customer Age

Answer – A
To get better performance on your underlying DynamoDB table, you should choose a partition key that would give an even distribution of values, and this would be the Customer ID.The below snapshot from the AWS Documentation gives some of the recommended partition key values.
Because of the AWS Documentation`s recommendations on better partition key values, all other options are invalid.
