# Cassandra
>[Cassandra](https://en.wikipedia.org/wiki/Apache_Cassandra) is a free and open-source, distributed, wide-column
> store, NoSQL database management system designed to handle large amounts of data across many commodity servers,
> providing high availability with no single point of failure. `Cassandra` offers support for clusters spanning
> multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.
> `Cassandra` was designed to implement a combination of `Amazon's Dynamo` distributed storage and replication
> techniques combined with `Google's Bigtable` data and storage engine model.

pip install cassandra-drive
