Bulk insert mutations with GraphQL

The Hasura GraphQL Engine provides efficient bulk insert mutations for creating new objects in a back-end database. It allows multiple objects of the same type to be inserted using a single SQL statement, and multiple objects of different types can be inserted using multiple insert mutation fields within the same mutation. If any mutation field fails, all mutation fields in that mutation will be rolled back, ensuring consistency. This feature is useful for applications requiring high performance and consistent database states during bulk inserts.
