Examples of CellNameType

org.apache.cassandra.db.composites.CellNameType
The type of CellNames. In the same way that a CellName is a Composite, a CellNameType is a CType, but with a number of method specific to cell names. On top of the dichotomy simple/truly-composite of composites, cell names comes in 2 variants: "dense" and "sparse". The sparse ones are CellName where one of the component (the last or second-to-last for collections) is used to store the CQL3 column name. Dense are those for which it's not the case. In other words, we have 4 types of CellName/CellNameType which correspond to the 4 type of table layout that we need to distinguish: 1. Simple (non-truly-composite) dense: this is the dynamic thrift CFs whose comparator is not composite. 2. Composite dense: this is the dynamic thrift CFs with a CompositeType comparator. 3. Simple (non-truly-composite) sparse: this is the thrift static CFs (that don't have a composite comparator). 4. Composite sparse: this is the CQL3 layout (note that this is the only one that support collections).
