@Target(METHOD)

public @interface DynamoDbAtomicCounter

Used to explicitly designate an attribute to be an auto-generated counter updated unconditionally in DynamoDB. By default, the counter will start on 0 and increment with 1 for each subsequent calls to updateItem. By supplying a negative integer delta value, the attribute works as a decreasing counter.
