OpsCenter 4.0 User Guide

Managing column families

When you create a column family in Cassandra using an application, the CLI, or CQL 2 or earlier, the column family appears in OpsCenter. You can use Schema to manage the column family.

You can also create one type of column family: the dynamic column family. Dynamic column families are those that do not specify column names or values when the column family is created. An application typically supplies this metadata. CQL 3, the default query language in Cassandra, does not support dynamic column families. Earlier versions of CQL and the CLI support dynamic column families.

This version of OpsCenter does not support defining static column families (per-column meta data), row key data types, or schema information for super column sub-columns described in Cassandra 1.0, or earlier.
