-------------------------------

             Summary: Add createTypeInformation to DynamicTableSink#Context
                 Key: FLINK-17693
                 URL: https://issues.apache.org/jira/browse/FLINK-17693
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Jark Wu
            Assignee: Jark Wu
             Fix For: 1.11.0


Currently, we have {{createTypeInformation}} on {{DynamicTableSource#Context}}, but not on {{DynamicTableSink#Context}}.
In some sink connectors, we need to buffer the {{RowData}} and flush at some interval. So we need to copy the {{RowData}} if object reuse is enabled, then the internal TypeInformation is needed to get the RowData TypeSerializer#copy.
