Retrying with the same improvements as in #6772, this time trying not to mess up with branches. @rlancemartin doing a fresh new PR from a branch with a new name. This should do. Thank you for your help! --------- Co-authored-by: Jonathan Ellis <jbellis@datastax.com> Co-authored-by: rlm <pexpresss31@gmail.com>

# Cassandra
|
|
|
|
>[Apache Cassandra®](https://cassandra.apache.org/) 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.
