Dan Burkert commented on KUDU-1631:
-----------------------------------
That's exactly what I'm proposing for this ticket. Spark has a separate filter
type for the prefix case ({{StringStartsWith}} vs {{StringEndsWith}} and
{{StringContains}}). So we could start taking advantage of this without any
changes to the Java client or tserver.
