=item --rds
Denotes the instance in question is on Amazon RDS. By default pt-kill runs
the MySQL command "kill" for L<"--kill"> and "kill query" L<"--kill-query">.
On RDS these two commands are not available and are replaced by function calls.
This option modifies L<"--kill"> to use "CALL mysql.rds_kill(thread-id)" instead
and L<"--kill-query"> to use "CALL mysql.rds_kill_query(thread-id)"
