I think what Ed asked is that having some CF with TimeUUIDType allowed him to
call get_slice with *any* date range, even though those values weren't inserted
in Cassandra.
I'm just a newbie here, but I think that this is not possible, and to do just
that you have to construct an additional index, maybe with this format:
DateRange = { // CF - TimeUUIDType
YYYYMMDD : { // Row, keyed by day, for example
time_uuid1 => nil,
time_uuid2 => nil,
time_uuid3 => nil,
...
}
}
...being time_uuid[123], the actual column names inserted in the other CF.
Is this correct?
