The following page has been changed by JoeStump: http://wiki.apache.org/cassandra/API The comment on the change is: Added notes about SlicePredicates. ------------------------------------------------------------------------------ === SlicePredicate === + A `SlicePredicate` is similar to a [http://en.wikipedia.org/wiki/Predicate_(mathematical_logic) mathematic predicate], which is described as: + + Sometimes it is inconvenient or impossible to describe a set by listing all of its elements. Another useful way to define a set is by specifying a property that the elements of the set have in common. + + `SlicePredicate`'s in Cassandra are described with either a list of `column_names`, a `SliceRange`, or both. + ||'''Attribute'''||'''Type'''||'''Default'''||'''Required'''||'''Description'''|| ||`column_names`||`list`||n/a||N||A list of column names to retrieve. This can be used similar to Memcached's "multi-get" feature to fetch N known column names. For instance, if you know you wish to fetch columns 'Joe', 'Jack', and 'Jim' you can pass those column names as a list to fetch all three at once.|| ||`slice_range`||`SliceRange`||n/a||N||A `SliceRange` describing how to range, order, and/or limit the slice.||
