Scott Carey commented on KAFKA-717:
-----------------------------------
{quote}As it stands now folks are already running 0.8.0-beta1 in
production{quote}
We have been up and running in production with 0.8 before beta-1, with Scala
2.10.1. About a month ago we moved to the most recent 0.8 with Scala 2.10.2.
2.10.x seems to provide a minor performance boost as well (faster Scala
collections).
Our load is not as high as LI and some others, but it is 250GB /day (after
compression), involves multiple partition topics, and heavily leverages the
mirroring. The performance was worse than 0.7.x at first, but it is catching
back up.
Compiling with 2.10.x actually highlights a LOT of warnings that could indicate
bugs in Kafka that 2.8.x compiler versions do not display. I am more worried
about those, possible bugs, than what upgrading to a newer Scala version brings.
I am much more concerned with the need for cross-compile for clients than for
the broker. The broker is isolated and can be tested on its own and default to
a newer Scala version. Consumer or Producer client libraries however have to
live in another application, and that application may have other dependencies
that constrain what version is appropriate.
