  • Keyspace inventory

    Keyspaces are the units of replication in Cassandra, but you can also think of them as the rough equivalent of databases.  The Data Modeling screen lists all existing keyspaces and provides an "Add Keyspace" button (highlighted) to add a new one.  Click it now.

  • Add keyspace

    The Add a Keyspace dialog should now pop up.  Enter a name for for your new keyspace, then click the "I would like to create a column family" checkbox (a column family is Cassandra's rough equivalent of a table) and click the "Save Keyspace" button.

  • All in the (column) family

    Now enter a name for your column family and set "column_type" to "Super" (a super column allows variable subcolumns in each row).  Pick data types for the "compare_with" and "default_validation class" options (I used "AsciiType" in this instance), then click the "Save Column Family" button.

  • How Do You Keep It All Up-To-Date?

    Having to run a separate GUI installer for every single package sounds like a scalability nightmare. Including your DBMS, Web server, load balancer, memory cache, scripting languages, scripting language add-ons, Web server add-ons, library dependencies ... that could easily mount up to hundreds of separate installers, which means hundreds of separate updates needing to be managed. On a Linux system, keeping it all-to-date involves little more than typing "apt-get update && apt-get upgrade".
