----------------------------------------
Summary: Support for equality and pushdown of filters on some UDTs
Key: SPARK-11196
URL: https://issues.apache.org/jira/browse/SPARK-11196
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Michael Armbrust
Today if you try and do any comparisons with UDTs it fails due to bad casting.
However, in some cases the UDT is just a thing wrapper around a SQL type
(StringType for example). In these cases we could just convert the UDT to its
SQL type.
Rough prototype:
