    • CASSANDRA_5_0

      public static final CassandraVersion CASSANDRA_5_0

    • CASSANDRA_4_1

      public static final CassandraVersion CASSANDRA_4_1

    • UNREADABLE_VERSION

      public static final CassandraVersion UNREADABLE_VERSION
      Used to indicate that there was a previous version written to the legacy (pre 1.2) system.Versions table, but that we cannot read it. Suffice to say, any upgrade should proceed through 1.2.x before upgrading to the current version.

    • NULL_VERSION

      public static final CassandraVersion NULL_VERSION
      Used to indicate that no previous version information was found. When encountered, we assume that Cassandra was not previously installed and we're in the process of starting a fresh node.
