> Along with MV (CASSANDRA-6477), time series aggregation or "rollups" are a common design pattern in cassandra applications.  I'd like to add CQL support for this along these lines:
> {code}
> CREATE MATERIALIZED VIEW stocks_by_hour AS
> SELECT exchange, day, day_time(1h) AS hour, symbol, avg(price), sum(volume)
> FROM stocks
> GROUP BY exchange, day, symbol, hour
> PRIMARY KEY  ((exchange, day), hour, symbol);
> {code}
