In-Depth Information
This turns out to be a very effective way to represent a set at the column family level.
When a new item is added to a set, the CQL abstraction simply adds a cell containing the
item appended to the appropriate clustering column/column name combination. Removing
items from the set is as simple as deleting the cell that encodes that item. In both cases,
Cassandra can do the right thing without having to read the existing contents of the set.
