sunjincheng commented on FLINK-6780: ------------------------------------ HI, [~wheat9] If I understand you correctly, your meant currently the external table source not implement both {{DefinedRowtimeAttribute}} and {{DefinedProctimeAttribute}} interface. e.g: {{CsvTableSource}}, when we using {{CsvTableSource}} by register {{registerExternalCatalog}}, {{FlinkLogicalTableSourceScan#deriveRowType}} will get None {{XXXtimeAttribute}}. Please tell me if i understand you incorrectly. And it's great if you can add test case for the error above. Thanks, SunJincheng > ExternalTableSource fails to add the processing time and the event time > attribute in the row type > ------------------------------------------------------------------------------------------------- > > Key: FLINK-6780 > URL: https://issues.apache.org/jira/browse/FLINK-6780 > Project: Flink > Issue Type: Bug > Reporter: Haohui Mai > Assignee: Haohui Mai > Priority: Critical > > 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>, ...)
