[erlang-questions] MySQL cluster

[Ulf Wiger (TN/EAB)]

I don't think I'd attempt something like that in mnesia without first
doing a lot of experimentation. While mnesia clusters should scale
fairly well towards some 50 or so nodes (perhaps more), with no more
than a few Gb of RAM capacity on each node, you won't get up to tens of
TB. Still, it's the disk storage, and backup/restore that would worry me
most.

My general assumption is that if you haven't carefully designed your
dbms to work well with that kind of data volume, most likely it won't
work.

Which DBMS is the best for terabyte data storage, I can't say. You have
a number of SQL DBMS:s to choose from.

BR,
Ulf W

We are prepairing rather big web project that will end up with tens of
TB of data.

Now, is it any worth to juice out Mnesia or just go with MySQL Cluster?

If we would use Mnesia we would use
PAX storage model vs. N-array storage
model.

Ulf... what do you think?
