Examples of CellName

org.apache.cassandra.db.composites.CellName
A CellName is a Composite, but for which, for the sake of CQL3, we distinguish different parts: a CellName has first a number of clustering components, followed by the CQL3 column name, and then possibly followed by a collection element part. The clustering prefix can itself be composed of multiple component. It can also be empty if the table has no clustering keys. In general, the CQL3 column name follows. However, some type of COMPACT STORAGE layout do not store the CQL3 column name in the cell name and so this part can be null (we call "dense" the cells whose name don't store the CQL3 column name). Lastly, if the cell is part of a CQL3 collection, we'll have a last component (a UUID for lists, an element for sets and a key for maps).
