Backend Clustering solution, recommendations

Hi, I was wondering if anyone could recommend a database clustering
solution for a massive warehouse. Rails/flex being the main front end.

Talking a few million rows, with queries that may touch a million rows
every few seconds.

I was giving some thought to a MySQL clustering project like Sequoia.

Or possibly just hiring a consulting firm to come in.

We’ve done some good size projects, but this will be the biggest we’ve
done to date.

– Thanks

We tried continuent a year or two ago and gave up. And our database was
small (couple hundred megs). We had three nodes and had problems with a
node crashing bringing the other nodes down. With the result being we
had
to power cycle each of the boxes. We never made it to production.

That said, it was about two years ago. Hopefully it’s improved, but
I’ve
been soured by the experience. Also, that wasn’t sequoia, it was their
commercial offering. No idea what difference that makes.

In our case we ended up just using a single master with multiple slaves
and the mysql_replication_adapter to spread the load.

That kind of replication is more than you really want to have on a
simple
master-master or master-slave replication. Your better off bringing in
someone with experience with that scale of DB, and using whatever they
recommend to you.
