I have a DB scenario that is very write intensive. Essentially its a
large scale hit counter of sorts. Currently we're running on a single
12core server with 6 SSDs in a RAID6 array. But we're looking for a way
to scale out write volume by adding more servers, hopefully as
conveniently as I might add Apache servers to a website. We see two
servers laboring so we add a third to the mix and so on.
I'm still looking at the various technologies available to me and was
wondering if someone out there had some suggestions on this front.
Although Galera Cluster says it scales for write loads too it also says
that all servers write the same data and make sure its committed by the
time the transaction is completed. So it seems like write performance
would never scale because all servers are doing the same write.
Maybe I'm missing something.
Anyhow some pointers would be appreciated.
If you're overwhelming one server (you haven't even begun to scale up
btw) you will have to shard. However, before you do that.. consider how
cheap 24 core servers with 10x FusionIO or similar SSDs would be versus
the cost in complexity of sharding.
Maybe take a look at Vitess, which helps shard things but keeps all the
good stuff you like about MariaDB/MySQL:
