Subject [jira] [Updated] (DRILL-20) Limit Operator Reference Implementation
Date Wed, 23 Jan 2013 02:52:12 GMT

     [ https://issues.apache.org/jira/browse/DRILL-20?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Merrick updated DRILL-20:

    Attachment: limit-reference.patch

Basic implementation of the Limit operator. 1-indexed such that a limit with {last = 0} always
returns nothing, and {last = 1} returns the first object - I chose this because it made sense
to me.

Doesn't do any validation on the values of first and last.

This is my first time digging around this codebase, feedback is very much appreciated.
