[jira] [Created] (ASTERIXDB-1281) Generic Interval Representation in ADM and AQL (phase 1)

Preston Carman created ASTERIXDB-1281:
-----------------------------------------

             Summary: Generic Interval Representation in ADM and AQL (phase 1)
                 Key: ASTERIXDB-1281
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1281
             Project: Apache AsterixDB
          Issue Type: Improvement
          Components: AsterixDB
            Reporter: Preston Carman
            Assignee: Preston Carman


The first phase of Generic Interval Representation in ADM and AQL will focus on areas seen by a user. The new format will also be open to supporting other interval types, although currently will only support date, time and datetime. Here are a few of the action items:

 - ADM printer and parser changed to support the new generic style format
    - interval(date("2012-01-01”), date(”2013-04-01”))
 - Add an "interval" AQL constructor to support the above format
 - Alter interval byte structure to support any interval type
   - byte tag, T start, T end
   - where T is currently only date, time and datetime
