Hi everyone, With the work to add Java 17 support for Cassandra, a new question around the future of UDF was raised. The scripted UDF was using Nashorn which is no longer packaged with the JDK. There are options to add new dependencies to Graal JS for example but it seems people are not sure that it is worth it. Please check the discussion on CASSANDRA-16895.
The following suggestion was made by Marcus and supported by other PMC members - "I think we should deprecate scripted UDFs now and drop them from the next major, but possibly provide hooks for people to write their own UDF "engines" and break out the current javascript implementation in to its own repository (but not ship it with Cassandra)." As a result we decided to engage with our users and created a Twitter survey. Results below: *We would love to understand how 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 - https://www.linkedin.com/feed/update/urn:li:activity:6886728406742970369?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A6886728406742970369%2C6886793921020608512%29&replyUrn=urn%3Ali%3Acomment%3A%28activity%3A6886728406742970369%2C6887421509485248512%29 Thoughts?
