> We observed that all streaming queries that refer to external tables fail when the Volcano
planner converting {{LogicalTableScan}} to {{FlinkLogicalTableSourceScan}}:
> {noformat}
> Type mismatch:
> rowtype of new rel:
> RecordType(<table schema>, TIMESTAMP(3) NOT NULL proctime) NOT NULL
> rowtype of set:
> RecordType(<table schema>, ...) NOT NULL
> {noformat}
> Tables that are registered through {{StreamTableEnvironment#registerTableSource()}} do
not suffer from this problem as {{StreamTableSourceTable}} adds the processing time / event
time attribute automatically.
