------------------------------------
Summary: Add Union operator to Table API.
Key: FLINK-2951
URL: https://issues.apache.org/jira/browse/FLINK-2951
Project: Flink
Issue Type: New Feature
Components: Documentation, Table API
Reporter: Chengxiang Li
Assignee: Chengxiang Li
Priority: Minor
Currently, union operation is supported by DataSet/DataStream API, not
available in Table API. To union two tables, user has to transform the
parameter input to DataSet/DataStream, for example:
{code:java}
val unionDs = left.union(right.toDataSet[Row])
{code}
It should be more API friendly to user if add union operation to Table API,
like:
{code:java}
val unionDs = left.union(right)
{code}
