Robert Stupp updated CASSANDRA-8289:
------------------------------------
Description:
Currently it's not possible to execute unit tests against UDFs nor is it
possible to debug them.
Idea is to provide some kind of minimalistic "framework" to execute at least
scalar UDFs from a unit test.
Basically that UDF-executor would take the information that 'CREATE FUNCTION'
takes, compiles that UDF and allows the user to call it using plain java calls.
In case of the Java language it could also generate Java source files to enable
users to set breakpoints.
It could also check for timeouts to identify e.g. "endless loop" scenarios or
do some byte code analysis to check for "evil" package usage.
For example:
{code}
import org.apache.cassandra.udfexec.*
public class MyUnitTest {
@Test
public void testIt() {
UDFExec sinExec = UDFExec.compile("sin", "java",
Double.class, // return type
Double.class // argument type(s)
);
sinExec.call(2.0d);
sinExec.call(null);
}
}
{code}
Note: this one is not intended to do some "magic" to start a debugger on a C*
node and debug it there.
