Subject:Re: mysql clustering -- any pitfalls ?
View as plain text  
It sounds like you've been handed a mandate that's difficult to
understand, but it could be because I don't understand the context, or
you may not understand your manager's real intention.  In any case,
"everyone is doing clustering" is certainly not accurate.  And every
"clustering" technology is actually built on some type of replication
(this is how data is duplicated into more than one place.)

There are a lot of pitfalls to clustering, the first being that you
might not understand exactly what you're asking the list to help you
with. Are you talking about changing to MySQL (NDB) Cluster?  This is
an entirely different set of technologies that takes a lot of
expertise and experience to administer, and it is by no means seamless
for the application.  This is not something to take lightly.

You may be interested in a relatively new clustering technology called
Galera, however, which is shipped as an integrated package in Percona
XtraDB Cluster:  The benefit
is that it's basically transparent for the application, and it's
familiar technology (with some added components) to administer.
