             Summary: Better error message to explain the upper limit of TimeWindow
                 Key: KAFKA-7446
                 URL: https://issues.apache.org/jira/browse/KAFKA-7446
             Project: Kafka
          Issue Type: Improvement
          Components: streams
    Affects Versions: 2.0.0
            Reporter: Jacek Laskowski


The following code throws a {{IllegalArgumentException}}.
{code:java}
import org.apache.kafka.streams.kstream.TimeWindows
import scala.concurrent.duration._
val timeWindow = TimeWindows
.of(1.minute.toMillis)
.advanceBy(2.minutes.toMillis)
{code}
The exception is as follows and it's not clear why {{60000}} is the upper limit (not to mention that {{AdvanceMs}} with the uppercase {{A}} did also confuse me).
{code:java}
java.lang.IllegalArgumentException: AdvanceMs must lie within interval (0, 60000].
at org.apache.kafka.streams.kstream.TimeWindows.advanceBy(TimeWindows.java:100)
... 44 elided{code}
I think that the message should be more developer-friendly and explain the boundaries, perhaps with an example (and a link to docs)?
