Subject [jira] [Commented] (CASSANDRA-7874) Validate functionality of different JSR-223 providers in UDFs
Date Mon, 08 Sep 2014 09:58:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14125363#comment-14125363
] 

Robert Stupp commented on CASSANDRA-7874:
-----------------------------------------

{{invokedynamic}} notes: Currently only Groovy and JRuby (on Java8) support invokedynamic.

* Groovy provides two variants - one with and one without InvokeDynamic - the readme in contains
instructions to use the one with InvokeDynamic.
* Jython currently targets Java6 only. They want to switch to J7 + invokedynamic in Jython
3.
* Scala 2.10 has J6 support only. 2.11 has experimental indy support. 2.12 introduces an upgrade
directly to Java8 (https://stackoverflow.com/questions/14285894/advantages-of-scala-emitting-bytecode-for-the-jvm-1-7).
* JRuby uses indy by default on J8 but not on J7 according to https://github.com/jruby/jruby/wiki/PerformanceTuning.

> CASSANDRA-7526 introduces ability to support optional JSR-223 providers like Clojure,
Jython, Groovy or JRuby.
> This ticket is about to test functionality with these providers but not to include them
in C* distribution.
> Expected result is a "how to" document, wiki page or similar.
