  <<Anchor(cli_keys)>>
  
  == Why does the 0.8 cli not assume keys are strings anymore? ==
- Prior to 0.8, there was no type metadata available for row keys, and the cli interface treated all keys as strings.  This made the cli unusable for the many applications whose rows were numberic, uuids, or other non-string data.

  0.8 added key_validation_class to the !ColumnFamily definition, similarly to the existing comparator for column names, and column_metadata validation_class for column values.  This both lets clients know the expected data type, and rejects updates with non-conformant values.
