----------------------------------
Summary: Need a zip function to combine coordinated lists
Key: DRILL-3222
URL: https://issues.apache.org/jira/browse/DRILL-3222
Project: Apache Drill
Issue Type: Bug
Reporter: Ted Dunning
It is often very useful to be able to turn a pair (or more) of lists into a
single list of pairs. Thus zip([a,b], [1,2]) => [[a,1], [b,2]].
The handling of short lists, more than two lists and so on is TBD, but the base
function is an important one.
One use case is in time series where storing times as one list and values as
another is very handy but processing these results would be much better done by
using flatten(zip(times, values)).
