[Solved] You run this command to create a DynamoDB table:aws dynamodb create-table --table-name Orders --attribute-definitions AttributeName=Id,AttributeType=N --key-schema... What is the most likely cause? | AWS

AWS - DynamoDB

You run this command to create a DynamoDB table:

aws dynamodb create-table --table-name Orders --attribute-definitions AttributeName=Id,AttributeType=N --key-schema AttributeName=OrderId,KeyType=HASH --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

But you get an error. What is the most likely cause?

AThe attribute definition and key schema attribute names do not match

BProvisioned throughput values are missing

CThe key schema is missing a RANGE key

DAttributeType should be 'S' for string, not 'N' for number

Step-by-Step Solution

Solution:

Step 1: Check attribute definitions and key schema names
The attribute definitions specify AttributeName=Id, but the key schema specifies AttributeName=OrderId. The names do not match, causing the error.
Step 2: Verify other potential issues
Provisioned throughput values are present (not B), a simple primary key with only HASH is allowed (not C), AttributeType=N is valid for numeric IDs (not D).
Final Answer:
The attribute definition and key schema attribute names do not match -> Option A
Quick Check:
Attribute names must match exactly [OK]

Quick Trick: Match attribute names exactly in definitions and key schema [OK]

Common Mistakes:

Assuming 'N' type is invalid
Expecting RANGE key for all tables
Missing provisioned throughput
