FAGIM SADYKOV updated CASSANDRA-14127:
--------------------------------------
Description:
Try to create UDF
{code:java}
CREATE OR REPLACE FUNCTION max_x_plus_y (input set<frozen<some_record>>) CALLED
ON NULL INPUT RETURNS some_record
LANGUAGE java AS '
return Collections.max(input, new Comparator<UDTValue>() {
@Override
public int compare(UDTValue first, UDTValue second) {
int firstsum = first.getInt("x")+first.getInt("y");
int secondsum = second.getInt("x")+second.getInt("y");
return Integer.compare(firstsum,secondsum);
}
});
';
{code}
I got error:
{code:log}
com.datastax.driver.core.exceptions.InvalidQueryException: Java source
compilation failed:
