Hi all,


I did a search through Google groups for the term
"Hadoop" and found only one post!


I would have thought that it was a fairly important
database given the client list if nothing else,
Google, Amazon, Twitter to name only a few of
the busiest sites on the planet that use it in some
shape or form.

Any reason for this - where would I go to find debates
on the pros and cons of Hadoop and similar?

TIA,


Paul...

Google doesn't use Hadoop per se; Google uses things
like GFS and MapReduce, which they built in-house and
have not released. The Hadoop project is an open source
reimplementation of various such Google ideas, based on
papers Google has published.

To a large extent, there's really nothing interesting in these
things; they are roughly 1960s era system services, including
the data management parts, but reimplemented such that
they allow for high scalability, and/or availability, through
very large scale redundancy.

Not much to discuss from a theory standpoint; not very
ambitious in anything except scale.

You might look for the mailing lists for the various projects,
if you want to talk about any of them specifically.
