A query handler is a component in software architecture, particularly in systems following the Command Query Responsibility Segregation (CQRS) pattern, that is responsible for processing and responding to data retrieval requests. It interprets incoming queries, interacts with the data source, and returns the requested information in a structured format. By separating query logic from command logic, query handlers help improve scalability and maintainability of applications.
