> The following creates a table that at the storage engine level, has "key" as the row
key, and evt as a time ordered list of columns within the row:
> create table test (key text, evt timestamp, primary key(key,evt)) with clustering order
by (evt asc);
> Given the ability to create slice tombstones (both implicitly by deleting collections
and supercolumns) as well as in thrift through a delete with a slice predicate.
> Given the schema above, the expected syntax to delete all columns with key "one" and
timestamp less than 1000 would be:
> delete from test where key='one' and evt < 1000;
> and if you did that as well as 
> delete from test where key='one' and evt > 1000;
> You would accomplish exactly what is being asked about (in terms of thrift and astyanax)
