Jark Wu closed FLINK-17399.
---------------------------
Fix Version/s: (was: 1.12.0)
Resolution: Won't Fix
The CsvTableSink is a legacy connector. The new
{{org.apache.flink.table.filesystem.FileSystemTableSink}} already supports
overwriting. Close this issue.
> CsvTableSink should also extend from OverwritableTableSink

> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: godfrey he
> Priority: Major
>
> {{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.
