     [ https://issues.apache.org/jira/browse/CASSANDRA-7924?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Stupp updated CASSANDRA-7924:
------------------------------------
    Attachment: 7924.txt

Patch with following changes:
* code generation for 'java' UDFs now emits a class that basically extends/implements {{UDFunction}}
* means: removal of reflection for 'java' UDFs + no need for invocation-API
* also (because it's trivial): 'class' UDFs now use java.lang.invocation instead of java.lang.reflection

> Refactor 'java' UDFs to optimize invocation. Goal is to remove reflection code. Implementation uses javassist to generate an instance of {{Function}} that can be directly used.
