Flipper is a tool for managing pairs of MySQL servers replicating to each other (commonly known as master-master replication or dual-master replication). Master-master replication is a great way of ensuring high availability for MySQL databases - it enables one half of the pair to be taken offline for maintenance work while the other half carries on dealing with queries from clients.
mysqlslap is a diagnostic program designed to emulate client load for a MySQL server and to report the timing of each stage. It works as if multiple clients are accessing the server.
