Hi, Otto, On Aug 18, Otto Kekäläinen wrote:
Yes, if the client doesn't support redirects, it'll work as before - that is, the client will be kicked out when the server is shut down and then the client will connect to a new server because, of course, if there's failover, there must be some way of telling clients what server to connect to. The error will be ER_SERVER_SHUTDOWN which is what old clients were always getting in this case. So, basically, for old clients there will be no changes whatsoever.
..which is not ideal. Some backwards compatibility would make the user experience much better.
I'm sorry, I don't understand that. I wrote that for old clients _nothing changes whatsoever_. It's a perfect backward compatibility, as if the new feature didn't exist at all, an ideal case, which is rarely even possible. How can it be more backward compatible than that? :) Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org
