I have the following setup :
Two galera nodes in a master <> master setup. On top of the galera nodes (same machine) I want to setup web servers that will do inserts into the database. Infront of the webservers/nodes I will put HAProxy for a load balancer to the webservers. I want the webservers to connect via localhost and do their inserts. On theory this setup should work fine but do you have any concerns and experience in this kind of setup? Should I expect problems with any kind ?
