Thibault Kruse commented on CASSANDRA-14004:
--------------------------------------------

fair enough, close if you want. Might still be worth thinking about how to deal with future
guava incompatibilities for cassandra 4.x +

> Using cassandra-all as a java library has the downside that it uses guava 18 methods
that have been removed from more recent guava versions, causing users to be forced to stick
with Guava <= 19.0.
> It would be nice for us if such method calls to guava could be replaced with code of
higher compatibility, for Casandra versions as far back as 3.0.x
> As an example replacing code like this
> Iterators.<RangeTombstone>emptyIterator()
> with
> Collections.emptyIterator()
> as done in
> https://github.com/krummas/cassandra/commits/marcuse/guava23
> Ensuring any cassandra-release is API compatible with several guava versions is more
painful, possibly a blacklist of method calls can be used via checkstyle to reduce the risk
of re-introducing version specific calls to guava methods.
