Ekaterina Dimitrova commented on CASSANDRA-16895:
-------------------------------------------------
Quick update - twitter survey:
_We would love to understand hope you use ApacheCassandra UDFs and UDAs._
_32 people responded as follows:_
* _We do not use them - 75%_
* _We only use Java UDFs - 22%_
* _We only use JS UDFs - 0%_
* _We use Java and JS UDFs - 3%_
We also received feedback on LinkedIN on the topic -

Next I am opening a discussion thread on the dev mailing list to get to some
consensus what we do with UDF. I already also found a simple workaround for the
ant script and scriptdef so that we don't need Nashorn/Graal/etc for those.

> Support Java 17
> ---------------
>
> Key: CASSANDRA-16895
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16895
> Project: Cassandra
> Issue Type: Task
> Components: Build
> Reporter: Ekaterina Dimitrova
> Assignee: Ekaterina Dimitrova
> Priority: Normal
>
> This ticket is intended to group all issues found to support Java 17 in the
> future.
> Upgrade steps:
> * [Dependencies
> |https://mvnrepository.com/artifact/org.apache.cassandra/cassandra-all/4.0.1]to
> be updated (not all but at least those that require an update in order to
> work with Java 17)
> * More encapsulated JDK internal APIs. Some of the issues might be solved
> with the dependencies updates
> * Currently trunk compiles if we remove the Nashorn dependency (ant script
> tag, used for the test environment; UDFs) . The oracle recommendation to use
> Nashorn-core won't work for the project as it is under GPL 2.0. Most probably
> we will opt in for graal-sdk licensed under UPL
> * All tests to be cleaned
> * CI environment to be setup
