Description: An entity mutation in GraphQL is an operation that allows modifying the data of a specific entity within a GraphQL schema. Unlike queries, which are used to retrieve data, mutations are designed to make changes, such as creating, updating, or deleting records. Each mutation is defined in the GraphQL schema and can include arguments that specify the details of the modification. For example, when performing a mutation to update a user, arguments such as the user ID and new values for their attributes can be provided. Mutations are fundamental for interacting with databases and backend systems, as they enable developers to manage application states efficiently. Additionally, mutations can return data, allowing clients to receive updated information immediately after making a change. This feature is particularly useful in real-time applications, where data synchronization is crucial. In summary, entity mutations are an essential part of GraphQL, providing a structured and efficient way to modify data in modern applications.
