             Summary: Use LogicalType to equals/hashcode in TableSchema
                 Key: FLINK-16270
                 URL: https://issues.apache.org/jira/browse/FLINK-16270
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
            Reporter: Jingsong Lee
            Assignee: Jingsong Lee
             Fix For: 1.11.0


 
{code:java}
- name: TableNumber2
    type: source
    $VAR_UPDATE_MODE
    schema:
      - name: IntegerField2
        type: INT
      - name: StringField2
        type: VARCHAR
      - name: TimestampField3
        type: TIMESTAMP
    connector:
      type: filesystem
      path: "$VAR_SOURCE_PATH2"
    format:
      type: csv
      fields:
        - name: IntegerField2
          type: INT
        - name: StringField2
          type: VARCHAR
        - name: TimestampField3
          type: TIMESTAMP
      line-delimiter: "\n"
      comment-prefix: "#"
{code}
Table like this will fail in SQL-CLI.
The root cause is we will convert the properties into CatalogTableImpl and then convert into properties again. The schema type properties will use new type systems then which is not equal to the legacy types.
