--------------------------------------
Glad to see that I'm not the only one convinced by this usage !
This probably needs to use different data structures for rowBetween() and
rangeBetween()
> Long values in Window function
> ------------------------------
>
> Key: SPARK-19451
> URL: https://issues.apache.org/jira/browse/SPARK-19451
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.1, 2.0.2
> Reporter: Julien Champ
>
> Hi there,
> there seems to be a major limitation in spark window functions and
> rangeBetween method.
> If I have the following code :
> {code:title=Exemple |borderStyle=solid}
> val tw = Window.orderBy("date")
> .partitionBy("id")
> .rangeBetween( from , 0)
> {code}
> Everything seems ok, while *from* value is not too large... Even if the
> rangeBetween() method supports Long parameters.
> But.... If i set *-2160000000L* value to *from* it does not work !
> It is probably related to this part of code in the between() method, of the
> WindowSpec class, called by rangeBetween()
> {code:title=between() method|borderStyle=solid}
> val boundaryStart = start match {
> case 0 => CurrentRow
> case Long.MinValue => UnboundedPreceding
> case x if x < 0 => ValuePreceding(-start.toInt)
> case x if x > 0 => ValueFollowing(start.toInt)
> }
> {code}
> ( look at this *.toInt* )
> Does anybody know it there's a way to solve / patch this behavior ?
> Any help will be appreciated
> Thx
