Sylvain Lebresne commented on CASSANDRA-8168:
---------------------------------------------
bq. In other words, extend Cassandra 2.1 EOL by at least one year longer than
we usually do. People stuck with Java 7 won't be able to go to C* 3.0 (until
they get unstuck), but won't have to deal with an abandoned Cassandra version,
either.
For what it's worth, I'm mildly a fan of this. It's a bit unclear to me that
getting java 8 in 3.0 is such a big deal, but buying one more year of painful
merge is a big deal. Getting nashorn is nice, but for UDF I think we'll end up
with mostly recommending people to use JAVA directly and so I don't think it's
a huge deal. As for CASSANDRA-5239, how sure are we that we'll have this done
in 3.0? And that {{CompletableFuture}} gives us something that guava's
{{ListenableFuture}} don't give us?

>
> This is to discuss requiring Java 8 for version >= 3.0
> There are a couple big reasons for this.
> * Better support for complex async work e.g (CASSANDRA-5239)
> http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/CompletableFuture.html
> * Use Nashorn for Javascript UDFs CASSANDRA-7395
