The fetch size is a hint for the driver to know how many rows at a time to
retrieve from the database. If you haven't given the driver any hints it
is set to zero meaning "If the fetch size specified is zero, the JDBC
driver ignores the value and is free to make its own best guess as to what
the fetch size should be." Older drivers used to report the number of
rows fetched in this method, but that was just an implementation artifact
at best and a bug at worst.
