Jark Wu commented on FLINK-24939:
---------------------------------
[~shenzhu0127], no, I don't think they should be stored in {{Catalog}}. A
catalog is an instance which is created from the properties, just like
`DynamicTableSource/Sink` is created from the {{CatalogTable}}. {{SHOW CREATE
TABLE}} get the properties from {{CatalogTable}} instead of adding
{{getProperties}} method to {{DynamicTableSource/Sink}}.
If we need to support this {{SHOW CREATE CATALOG}}, I think a better idea is
convert the CREATE CATALOG DDL into a structure (just like CatalogTable) and
save it in {{CatalogManager}}. {{SHOW CREATE CATALOG}} should look for the
structure and build the DDL string.
> Support 'SHOW CREATE CATALOG' syntax
