.NET on AWS Blog When you migrate .NET applications from SQL Server to Amazon DynamoDB, your existing pagination patterns need adaptation. .NET applications commonly use page number navigation with Language Integrated Query (LINQ) Skip() and Take() methods, which rely on SQL Server’s OFFSET/FETCH NEXT clauses and indexed ordering to provide consistent navigation experiences.

Introduction Web applications use counter operations to deliver interactive user experiences. Whether tracking social media engagement metrics or managing e-commerce inventory levels, these operations must be both reliable and scalable. This post walks you through two architectural patterns that deliver predictable performance. To illustrate these patterns, let us consider a social media application post-liking feature.

In Part 1 of our series, we explored how to effectively migrate from SQL to Amazon DynamoDB. After establishing data modeling strategies discussed in Part 2, we now explore key considerations to analyze and design filters, pagination, edge cases, and aggregations, building upon the data models designed to create an efficient data access layer. This component bridges your application with DynamoDB features and capabilities.
