Hello all, After playing with the idea of 'abandoning ship' in favor of IBM DB2 or Oracle, we deiced to stick with mySQL, due its simplicity and investment in time and experience we have put into it.
Our company needs a HA solution for ensuring 24x7 operation for the mySQL server instances. As it is, there are are two solutions available for the problem: Emic Networks's EAC for mySQL and MySQL's Cluster. The Emic solution seems to work but is way too expensive for our budget (around 4k$ for each 2CPUs node). So we need to either go with NDB or try to get replication to work properly. Here is a list of questions: o How 'stable' is MySQL cluster (NDB) ? Is it ready for enterprise use? Or even tested? o Does the memory size limit the data we can manage? If it is a memory based solution it should mean that it can handle of a very limited number of databases/tables/rows, based on the available memory of the nodes. o Is there some sort of tight integration planned for mySQL cluster and mySQL server ? Perhaps in 5.0 ? o When is adding/removing nodes on the fly scheduled for implementation? Without such a feature the system would have to be shutdown - therefore not a complete HA solution. o Has anyone gotten replication to work right? Perhaps Multi-Master replication?
