database-performance

To optimize database queries and resolve slow load times, you should refactor your data access layer by avoiding N+1 queries, applying row limits, using AsNoTracking, and performing joins directly in SQL.

The CQRS pattern improves database performance by separating read and write models, allowing you to optimize query structures specifically for data retrieval or persistence rather than using a single model for both.

To avoid N+1 query problems in EF Core and Dapper, you should perform joins in SQL to retrieve related data in a single round trip instead of issuing separate queries for each entity relationship.

You should use AsNoTracking for database access pattern optimization when executing read-only queries, as it prevents the framework from tracking entity state and reduces memory overhead for improved performance.

Yes, this database optimization guidance works with both EF Core and Dapper, providing specific strategies like performing SQL joins and applying row limits to address performance pitfalls across both data access technologies.

Implementing CQRS for data access layer refactoring introduces complexity by requiring separate models for reads and writes, which is best suited for scenarios experiencing significant performance bottlenecks rather than simple CRUD operations.
