Subject [jira] [Commented] (CASSANDRA-11873) Add duration type
Date Mon, 23 May 2016 09:25:12 GMT


Benjamin Lerer commented on CASSANDRA-11873:

One interesting question is what type of text representation do we want to support for duration.
The simplest approach would be to support only a number and a time unit: days ({{d}}), hours
({{h}}), minutes ({{m}}), seconds ({{s}}), milliseconds ({{ms}}) and micro seconds ({{┬Ás}}).
A slightly more complex one would be to allow the combination of multiple simple expressions
like: 2d8h (2 days and 8 hours).

> 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.
