Question

What are some best practices for designing schemas in DynamoDB?

Answer 1

• Use a composite key: Leverage partition and sort keys to enable more flexible queries.
• Dynamically distribute traffic: Choose partition keys that help evenly distribute read and write traffic.
• Avoid hot partitions: Ensure your data distribution is uniform to avoid throttling.
• Use indexes wisely: Utilize secondary indexes to improve query flexibility but be mindful of costs.
• Plan for item size: Keep item sizes small to optimize read and write efficiency.
• Optimize for access patterns: Design your schema based on how the data will be accessed to optimize performance.
