Hi Zhenghua,
For external systems with schema, I think the schema information is
available most of the time and should be the single source of truth to
programmatically mapping column precision via Flink catalogs, to minimize
users efforts creating schema redundantly again and avoid any human erro
Hi Jingsong Lee

Hi Zhenghua,
I think it's not just about precision of type. Connectors not validate the
types either.
Now there is "SchemaValidator", this validator is just used to validate
type properties. But not for connector type support.
I think we can have something like "DataTypeValidator" to help connecto
Hi dev,
I'd like to kick off a discussion on a mechanism to validate the precision
of columns for some connectors.
We come to an agreement that the user should be informed if the connector
does not support the desired precision. And from the connector developer's
view, there are 3-levels informat
