Databases "This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster)."

Is it safe to migrate from 4.1 to 5.0? I need to use View.

5.0.x is marked as production ready so it should be fine. I have read that 5.x performance can be lower then 4.1 if used without stored procedures, but I haven't run any benchmarks myself.

Instead of running benchmarks maybe it would be better to test it on real-world applications.

The migration issue for me is not about performance, but about compatibility. I don't want the migration break many applications.
