Alexey Serbin updated KUDU-2969:
--------------------------------
Issue Type: New Feature (was: Bug)
> UDF support for scans
> ---------------------
>
> Key: KUDU-2969
> URL: https://issues.apache.org/jira/browse/KUDU-2969
> Project: Kudu
> Issue Type: New Feature
> Components: tablet, tserver
> Affects Versions: 1.11.0
> Reporter: Adar Dembo
> Priority: Major
>
> 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].
