> In order to support Blink batch and temporal table join, we need some new
> source&sink interfaces and changes about TableSchema.
> - {{AsyncTableFunction}}: used as async lookup function, to support async
> temporal table join (i.e. dimension table join.).
> - {{LookupableTableSource}}: The {{LookupableTableSource}} interface adds
> support for the table to be accessed via key column(s) in a lookup fashion in
> order to support temporal table join.
> - {{BoundedTableSource}}: used for batch table source, returns a bounded
> DataStream, not a {{InputFormat}}, because we also want to reuse existing
> streaming source implementation to support bounded source, for example:
> bounded Kafka source.
> - {{BoundedTableSink}}: used for batch table sink, emit a bounded
> DataStream, not a {{OutputFormat}}. The reason is the same as above.
