DynamoDB - Access Patterns and Query Optimization

Which of the following is a correct way to design a partition key to prevent hot partitions?

AUse the same timestamp as the partition key for all writes

BUse a static string as the partition key for all items

CAdd a random suffix or hash to the partition key

DUse a sequential number as the partition key without variation

Step-by-Step Solution

Solution:

Step 1: Review partition key design principles
To prevent hot partitions, keys should distribute traffic evenly, not be identical or sequential.
Step 2: Identify the correct method
Adding a random suffix or hashing the key spreads requests across partitions.
Final Answer:
Add a random suffix or hash to the partition key -> Option C
Quick Check:
Partition key design = add randomness or hash [OK]

Quick Trick: Add randomness or hash to partition key to balance load [OK]
