---------------------------------
Summary: opinion on refactoring ListenableFuture to Java 8
CompletableFuture
Key: CASSANDRA-8565
URL: https://issues.apache.org/jira/browse/CASSANDRA-8565
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Yu Lin
Priority: Minor
Hi, I'm doing research on new concurrent constructs in Java 8. I found
CompletableFuture in Java 8 has the same functionality as Guava
ListenableFuture. But CompletableFuture is much nicer because it comes together
with Lambda expression in Java 8, and it is monadic, which makes the code more
readable and cleaner. Also, it provides more ways to compose different tasks.
Therefore, using CompletableFuture instead of ListenableFuture is better for
future extension and maintenance of the code.
I also created a pull request on the Github repo and refactored one
ListenableFuture instance, so you can see the diff (you don't have to apply
that patch):
https://github.com/apache/cassandra/pull/50
I'm just wondering your opinion on this kind of refactoring (or migrating the
code from Java 7 to Java 8). Do you think the refactoring is useful? Do you
have any plan to use Java 8?
