Hi Devs,
I would like to know what is the current roadmap of making
CalendarInterval comparable and orderable again (SPARK-29679,
SPARK-29385, #26337).
With #27262, this got reverted but SPARK-30551 does not mention how to
go forward in this matter. I have found SPARK-28494, but this seems to
be stale.
While I find it useful to compare such intervals, I cannot find a way to
work around the missing comparability. Is there a way to get, e.g. the
seconds that an interval represents to be able to compare intervals? In
org.apache.spark.sql.catalyst.util.IntervalUtils there are methods like
getEpoch or getDuration, which I cannot see are exposed to SQL or in the
org.apache.spark.sql.functions package.
Thanks for the insights,
Enrico
