AWS - DynamoDB

Which of the following is the correct way to define a DynamoDB table with a partition key named UserId and a sort key named OrderDate in AWS CLI?

aws dynamodb create-table --table-name Orders --attribute-definitions AttributeName=UserId,AttributeType=S AttributeName=OrderDate,AttributeType=S --key-schema ...

A--key-schema AttributeName=UserId,KeyType=HASH AttributeName=OrderDate,KeyType=RANGE

B--key-schema AttributeName=OrderDate,KeyType=HASH AttributeName=UserId,KeyType=RANGE

C--key-schema AttributeName=UserId,KeyType=RANGE AttributeName=OrderDate,KeyType=HASH

D--key-schema AttributeName=OrderDate,KeyType=RANGE AttributeName=UserId,KeyType=HASH

Step-by-Step Solution

Solution:

Step 1: Identify partition and sort key roles
The partition key uses KeyType=HASH and the sort key uses KeyType=RANGE in DynamoDB key schema.
Step 2: Match keys to names
UserId is the partition key (HASH), OrderDate is the sort key (RANGE).
Final Answer:
--key-schema AttributeName=UserId,KeyType=HASH AttributeName=OrderDate,KeyType=RANGE -> Option A
Quick Check:
Partition=HASH, Sort=RANGE [OK]

Quick Trick: Partition key = HASH, sort key = RANGE in key schema [OK]

Common Mistakes:

MISTAKES

Swapping HASH and RANGE key types
Mixing up partition and sort key names
