Annotation Interface Fetch

@Documented @Retention(RUNTIME) @Target(METHOD) public @interface Fetch
Hint to drivers to use the given fetch size for streaming repository methods. - For JDBC: applied to methods returning java.util.stream.Stream<T>, it will call PreparedStatement#setFetchSize(int). - For R2DBC: applied to methods returning reactor.core.publisher.Flux<T>, it will call io.r2dbc.spi.Statement#fetchSize(int). - For Hibernate: applied to methods returning java.util.stream.Stream<T>. Implementations may ignore the hint if unsupported by the underlying driver.
