Which JDBC feature allows you to execute a SQL query asynchronously?

The Statement.executeAsync() method allows developers to execute SQL queries asynchronously in JDBC. This feature enables non-blocking database operations, meaning that the application can continue processing other tasks while waiting for the database query to complete. Asynchronous execution is particularly beneficial in scenarios where long-running queries or high-latency databases are involved.

By using executeAsync(), developers can improve the responsiveness and performance of their applications, especially in multi-threaded environments or when dealing with large datasets. This method returns a CompletionStage, which can be used to handle the result of the query once it is completed, allowing for more flexible and efficient processing.

Asynchronous query execution is a powerful tool for optimizing database interactions in Java applications. It allows for better resource utilization and can lead to significant performance improvements in applications that rely heavily on database operations.
