Istvan Szegedi details installation of both Cassandra and OpsCenter along with some basic operations.
From the post:
Cassandra – originally developed at Facebook – is another popular NoSQL database that combines Amazon’s Dynamo distributed systems technologies and Google’s Bigtable data model based on Column Families. It is designed for distributed data at large scale.Its key components are as follows:
Keyscape: it acts as a container for data, similar to RDBMS schema. This determines the replication parameters such as replication factor and replication placement strategy as we will see it later in this post. More details on replication placement strategy can be read here.
Column Familiy: within a keyscape you can have one or more column families. This is similar to tables in RDBMS world. They contain multiple columns which are referenced by row keys.
Column: it is the smallest increment of data. It is a tuple having a name, a value and and a timestamp.
Another information center you are likely to encounter.
