[Caml-list] PlasmaFS, PlasmaKV, and MapReduce, version 0.5.1

[Caml-list] PlasmaFS, PlasmaKV, and MapReduce, version 0.5.1

[Gerd Stolpmann]

Hi,

I've just released Plasma-0.5.1, fixing a possible lock-up.

General information about Plasma:

Plasma consists now of three parts, namely PlasmaFS, PlasmaKV, and Plasma
Map/Reduce:

      * PlasmaFS is a distributed replicating filesystem. Unlike other
        such filesystems, it is transactional and exhibits transactions
        to the user. Also, it implements almost all of what is known as
        POSIX semantics, and it is mountable.
      * PlasmaKV is a key/value database on top of PlasmaFS. It is
        designed for ultra-high read workloads, and offers interesting
        properties borrowed from PlasmaFS (e.g. replication and ACID
        transactions).
      * Plasma Map/reduce implements a variant of the popular
        data processing scheme.

All pieces of software are bundled together in one download. The
project page with further links is

http://projects.camlcity.org/projects/plasma.html

There is now also a homepage at

http://plasma.camlcity.org

THIS IS NOW A BETA RELEASE! I'm searching for testers. Whoever has
access to a cluster please check Plasma out!

Plasma is installable via GODI for Ocaml 3.12.

For discussions on specifics of Plasma there is a separate mailing list:

Any plans to support fuse so the filesystem can be mounted locally?

You can already do this via NFS (V3). This is only a mild additional
overhead, and the Linux NFS client supports bigger blocksizes than fuse
(1M vs. 128K).

Fuse is on my list but low priority for now.
