Key: DRILL-7886
URL: https://issues.apache.org/jira/browse/DRILL-7886
Project: Apache Drill
Issue Type: Improvement
Components: Functions - Drill
Affects Versions: 1.18.0
Reporter: ye tian
Fix For: 1.18.0
Hi I'm developing Apache Drill UDFs. I need a self-defined class in the
workspace of my aggregate function. But UDAF's workspace does not support
variables other than ValueHolders. So my question is: is it able to write a
ValueHolders for self-defined classes? Any instructions are also welcome.
