[Ruby] Experience with BigTable-like products

[Alex Vollmer]

I'm looking into some BigTable-like products for a project and wondered if
anyone on the list had particular experience with any of the tools out there
and had any recommendations or warnings. Right now I'm looking at MogileFS,
CouchDB and HDFS (Hadoop Distributed File System). Are there others that
people have worked with? I'm looking for something that is
language-agnostic, distributed, persistent and redundant. That should be
easy, right? ;-)

TIA,

Alex V.
