Hi,
I'm writing this because I realize this stuff needs users to comment on before
it gets set into an ABI release.
Hive 2.2.0 will check if a user's UDF has a vectorized version before wrapping
it row-by-row.
@VectorizedExpressions(value = { VectorStringRot13.class })
https://github.com/apache/hive/tree/master/itests/custom-udfs/udf-vectorized-badexample
I have checked in a fairly bad example of this, with the vectorized &
non-vectorized UDF returning different values for testing purposes.
User & dev feedback would be welcome on extending base classes like the
IStringUnaryUDF.
Cheers,
Gopal
