While "clustering" in some circles may be an open-ended buzzword --
mainly the commercial DB marketing crowd -- there are concepts beneath
the bull that are even inherent in the name. However, I understand
your point.
>From what I've researched, the concepts and practices seem to fall
under one of two abstract categorizations: fail-over (ok...
high-availability), and parallel execution (high-performance... sure).
While some consider the implementation of only one of these to qualify
a cluster, others seem to demand that a "true" cluster must
implement both.
What I'm really after is a DB setup that does fail-over and parallel
execution. Your setup sounds like it would gracefully handle the
former, but cannot achieve the latter. Perhaps I'm simply asking too
much of a free software setup.
Thanks for your response.
