@jianbzhou That would be possible, but is not typically what storm
guarantees. Additionally you would have to configure a lot of other components
to maintain that ordering. Kafka itself does not guarantee this unless you
only have a single partition. Storm cannot guarantee it internally unless you
are sending downstream to a single bolt instance, or you have a custom grouping
that is smart enough to be able to take it into account.
Ordering guarantees are very difficult in distributed systems and if you
can design your system handle out of order data it will be much more robust and
scale better.
> As a storm developer I’d like to use the new kafka consumer API (0.8.3) to
> reduce dependencies and use long term supported kafka apis
