• Understand Access Patterns: Identify how your application will access data, including read and write operations as well as query patterns. Knowing these patterns helps in structuring your tables effectively, which is essential for maximizing the return on investment (ROI) for your business. Utilizing dynamodb data modeling techniques can greatly enhance this process.
• Use Composite Keys: DynamoDB allows you to create tables with composite primary keys (partition key and sort key). This enables you to store related items together and retrieve them efficiently. For example, if you have a table for orders, you can use UserID as the partition key and OrderID as the sort key. This design can significantly reduce latency and improve user experience, leading to higher customer satisfaction and retention. A dynamodb data modeler can assist in visualizing this structure.
• Denormalization: Unlike relational databases, denormalization is often beneficial in DynamoDB. Store related data together to minimize the number of read operations. For instance, instead of having separate tables for users and their orders, you can embed order details within the user record. This approach not only simplifies data retrieval but also reduces costs associated with multiple read operations. This is a key aspect of dynamodb modeling best practices.
• Global Secondary Indexes (GSIs): Use GSIs to support additional query patterns without duplicating data. GSIs allow you to query data using different attributes, enhancing flexibility. This capability can be leveraged to create tailored analytics and reporting solutions that provide deeper insights into business performance. Understanding dynamodb consistency models is important when working with GSIs.
• Capacity Planning: Estimate your read and write capacity units based on expected traffic. This helps in avoiding throttling and ensures that your application remains responsive. Effective capacity planning can lead to cost savings and improved operational efficiency, ultimately contributing to a greater ROI. Consider using a dynamodb modeling tool to assist in this process.
