Benjamin Lerer commented on CASSANDRA-11873:
--------------------------------------------
I am -1 on this. I think those syntaxes are more complex than needed. In my
opinion {{now() - 3d}} will be easily understood by everybody and I do not
think that there is a need to have to write {{now() -3 day}}. In the case of
CASSANDRA-11871 I found that the {{INTERVAL}} syntax is making the query much
more verbose and less readable: {{GROUP BY floor(time, INTERVAL '1' HOUR)}}.
> Add duration type

> 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.
