MassiveGit

MassiveGit - revision controlled database.

Implementation

MassiveGit implements Git Object Model on top of Riak [http://basho.com/products/riak-overview/]. In future other backends may be implemented.

Currently MassiveGit depends on custom version of riak-js module [https://github.com/podviaznikov/riak-js]. Install it from this repository.

Use cases

There are variety of use cases where it can be used:

• GitHub
• CircuitHub
• WikiPedia
• shapesmith (MCAD)

Basically any case where you need to store revisioned versions of your data. With MassiveGit you get nice abstraction layer which allows you to deal with data in terms of Git: Commit, Tree, Blob, Tag.

Additional materials

We have video and slide from London Node.js User Group: http://lanyrd.com/2011/lnug-october/skgpw/.

Check them for initial introduction.

Tips

Remove riak data from this directory:

/var/lib/riak/leveldb

Configurations

Please updated js_max_vm_mem and js_thread_stack to 512 MB on your app.config.

See [http://wiki.basho.com/MapReduce.html] for details how to do this and why.

Since we are using secondary indexes please make following change in the riak app.config: change the storage backend to riak_kv_eleveldb_backend.
