-----------------------------------
Summary: Add a union type
Key: FLINK-8129
URL: https://issues.apache.org/jira/browse/FLINK-8129
Project: Flink
Issue Type: New Feature
Components: Table API & SQL
Reporter: Timo Walther
Many input formats like Avro or ORC support union types to work with different
types in one field. It might make sense to support those use cases in the Table
& SQL API as well. A union type is similar to an {{Either}} type but takes an
arbitrary number of possible types. It might considers {{null}} as a type. It
is up for discussion if we want to add this type to {{flink-core}}.
