You could write to an InnoDB frontend with master/master replication at
each site, and slave off the local InnoDB server to your local cluster
at each site.
Would make your writes limited by your InnoDB server performance and
remote replication speed, but reads would run at cluster speeds and
Keep in mind that all "cluster" solutions are vulnerable to a single power
failure, earthquake, flood, tornado, etc.
To "protect" from such, you need a hot backup located remotely from the "live"
setup. This introduces latency that will kill performance -- all cluster
solutions depend on synci
Hello,
As far i can understand by your post, you need a high availability mysql
cluster with large capacity.
For having high availability you need something that can give you
multi-master replication between two or more mysql servers.
In my knowledge there are three solutions that can give yo

It sounds to me like you need a combination of sharding (one master per
client or set of clients) combined with multiple slaves (one for backups
only). If y

We are actually facing both capacity and availability issues at the same time.
Our current primary server is a Dell T410 (single processor, 32 GB memory) with
a Dell T310 (single processor, 16GB memory) as backup. Normally, the backup
server is running as a slave to the primary server and we ma
