---------------------------------
Assignee: (was: Benedict)
> Standardize use of collections, streams, iterables, functions, predicates etc.

> Key: CASSANDRA-10063
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10063
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Benedict
> Fix For: 3.x
>
>
> With the advent of Java 8 we have a lot of different mechanisms for achieving
> the same expression of ideas. We should standardize on (approximately) a
> single approach across the codebase, as this will help clarity, reduce
> development time (with less indecision about which set of tools to use, and
> how to interface between the two), and improve icache occupancy.
> The problem is exacerbated by the difficulty of interfacing between the two
> paradigms, and this (IMO) introduces an unnecessary cognitive burden when
> they inevitably meet. We should pick one and fill in whatever we're missing
> to make it fit all of our needs. We should perform a bit of due diligence
> about the implementation details of any utility methods we use also, as
> having dived into a handful they are occasionally.... surprising. And
> probably not how we would implement them (take {{Ordering.leastOf}} as an
> example).
> Since it is the future, I think we should be standardising on the JDK8
> Streams API where possible. There are a couple of rough edges with
> interfacing with it in some places, but we can smooth them and the result
> should be much more legible code.
> This really should not be a huge amount of work, and I expect will pay
> dividends quite quickly.
