Tyler Hobbs commented on CASSANDRA-11873:
-----------------------------------------

Will you be able to bind to the duration? As in:
session.prepare("SELECT * FROM myTable WHERE pkey=5 AND clustCol > now() - ?")
or
session.prepare("SELECT * FROM myTable WHERE pkey=5 AND clustCol > now() - ?h")
{quote}
You will be able to use the first example you listed. The unit suffix is part
of the value, so the second example wouldn't work.

> For CASSANDRA-11871 or to allow queries with {{WHERE}} clause like:
> {{... WHERE reading_time < now() - 2h}}, we need to support some duration
> type.
> In my opinion, it should be represented internally as a number of
> microseconds.
