--------------------------------
Summary: UDF support for scans
Key: KUDU-2969
URL: https://issues.apache.org/jira/browse/KUDU-2969
Project: Kudu
Issue Type: Bug
Components: tablet, tserver
Affects Versions: 1.11.0
Reporter: Adar Dembo
It would be nice if Kudu supported some form of user-defined functions (UDFs)
for use in scans. These could be used for custom comparisons, or for
comparisons between multiple columns (rather than between columns and constant
values).
Impala supports [both Java-based and native
UDFs|https://impala.apache.org/docs/build/html/topics/impala_udf.html]. We
could explore doing something similar, or an approach with an IR like
[Weld|https://www.weld.rs].
