Scenario: You are building a high-performance application that requires reading a large dataset from a database. How can you efficiently achieve this using a data reader?

Utilizing SqlDataReader's Forward-Only Cursor mode provides the most efficient way to read a large dataset from a database. This mode allows for a single-pass read-through of the data, reducing the overhead associated with maintaining a scrollable cursor or performing asynchronous operations. Scrollable cursors, UpdateBatchSize property, and ExecuteReaderAsync method might introduce unnecessary overhead or complexity in scenarios where a simple, efficient read-through is sufficient.
