• What is it?

    Pandra (PHP-Cassandra) is a light-weight PHP based create/read/update/delete (CRUD) layer for the Cassandra distributed datastore.
    Sitting ontop of the generated Thrift Interface files, it suits as a factory patterned rapid prototyping tool.
  
    "Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store.
     Cassandra brings together the distributed systems technologies from Dynamo and the data model from Google's BigTable.
     Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra provides a ColumnFamily-based data model richer than typical key/value systems.
  
     Cassandra was open sourced by Facebook in 2008, where it was designed by one of the authors of Amazon's Dynamo.
     In a lot of ways you can think of Cassandra as Dynamo 2.0. Cassandra is in production use at Facebook but is still under heavy development."
     - http://incubator.apache.org/cassandra/
  
    Pandra can be installed and interfaced in a few minutes, building your API or web service on a highly redundant datastore can be realised with relative ease.
