Brian Hess commented on CASSANDRA-11873:
-----------------------------------------
So, one question about syntax. SQL has a time interval type with its own
syntax. Instead of inventing additional syntax, what about taking on the
Postgres or Oracle/SQL-Standard syntax.
For example, Postgres uses "1 day ago" or "-1 day" (or hour, minute, etc):
https://www.postgresql.org/docs/current/static/datatype-datetime.html
Oracle uses "INTERVAL '1' HOUR":
https://docs.oracle.com/cd/B28359_01/server.111/b28286/sql_elements003.htm#i38598
I suggest we choose something similar to one that exists, rather than create
our own new syntax.

> 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.
