"This series introduces partial support for range deletions. This allows
deletion operations such as
delete from cf where p=1 and c > 0 and c <= 3.
This series only adds support for single-column range restrictions.
We enforce that both range bounds be specified, because we can't represent
infinite bounds in the current sstable format. Such bounds are represented
as a prefix with no components, with the bound_kind informing whether they
are a bottom of top bound.
We're currently unable to serialize an infinite bound in such a way that it
would be correctly interpreted by Cassandra 2.2.x. A serialized bound is a
composite with a (<length><value><EOC>)+ format. While we could technically
represent the bottom bound, the top bound, if written as a single component
with 0 bytes in size and some EOC, would always sort before other values.
The same would happen if represented as an empty (no components) composite,
because in Cassandra 2.2.x those always have EOC = NONE.
This limitation should stay in place until we can properly represent range
tombstones in the storage format."
