[jira] [Created] (FLINK-17399) CsvTableSink should also extend from
OverwritableTableSink
godfrey he created FLINK-17399:
----------------------------------
Summary: CsvTableSink should also extend from OverwritableTableSink
Key: FLINK-17399
URL: https://issues.apache.org/jira/browse/FLINK-17399
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Reporter: godfrey he
Fix For: 1.11.0
{{CsvTableSink}} has supported {{writeMode}} which could be {{OVERWRITE}} or {{NO_OVERWRITE}}. When we execute "INSERT OVERWRITE csv_table_sink xx", planners will check whether a table sink is an {{OverwritableTableSink}}.
Now {{CsvTableSink}} does not extend from {{OverwritableTableSink}}, so we can't execute above statement.
