Jake Maes updated SAMZA-1277:
-----------------------------
Description:
The current design forces users to do stuff like this (I can provide more than
a few examples already)
{noFormat}
List<MessageStream<GenericRecord>> xTrackingMonitoringEvents = new
ArrayList<>();
// ... populate the list
MessageStream<GenericRecord> initialInputStream =
xTrackingMonitoringEvents.remove(xTrackingMonitoringEvents.size() - 1);
Collection<MessageStream<? extends GenericRecord>> otherStreams =
(Collection<MessageStream<? extends GenericRecord>>) (Object)
xTrackingMonitoringEvents;
initialInputStream
.merge(otherStreams)
// .do other stuff
{noFormat}
^ eww. Removing one item from the array so it can be used as the initial
message stream seems to cause pain.
Lets see if we can come up with a cleaner way to do merge()
