Gopal V commented on HIVE-11462:
--------------------------------
[~hsubramaniyan]: #1 & #2 are optimizations, until we're sure that the
transient fields are not an issue, I'll leave them generated as-is.
Those shouldn't be a performance issue provided the constant propogate works
correctly.
> GenericUDFStruct should constant fold at compile time

> Key: HIVE-11462
> URL: https://issues.apache.org/jira/browse/HIVE-11462
> Project: Hive
> Issue Type: Bug
> Components: UDF
> Affects Versions: 2.0.0
> Reporter: Gopal V
> Attachments: HIVE-11462.1.patch, HIVE-11462.WIP.patch
>
>
> HIVE-11428 introduces a constant Struct Object, which is available for the
> runtime operators to assume as a constant parameter.
> This operator isn't constant folded during compilation since the UDF returns
> a complex type, which is logged as warning by the constant propogation layer.
