A ReadStream of Rows from the underlying RDBMS. This class follows the ReadStream semantics and will automatically
close the underlying resources if all returned rows are returned. For cases where the results are ignored before the
full processing of the returned rows is complete the close method **MUST** be called in order to release underlying
resources.
The interface is minimal in order to support all SQL clients not just JDBC.
 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**
