TypeId -> Type conversion of a ConnectorViewDefinition.ViewColumn

[gw-vastdata]

Hi,

We're adding view support for our connector, and I see that while ColumnMetadata holds a Type, a ConnectorViewDefinition.ViewColumn only holds a TypeId.

The Type -> TypeId translation is straightforward, so it is possible to manually reverse it, but I wanted to be sure I'm not missing a better way to achieve this - the end goal is to translate the TypeIds to Arrow Fields to get a complete schema, which is required by our backed to actually create the view.

Any recommendations?

Follow-up question - why do views and materialized views use only the TypeIds and not the original Types?

Thanks :)

Update: We added trino-main as a dependency to reuse io.trino.metadata.TypeRegistry. Still feels like a hack, but at least it ensures consistency.

Update 2: We dropped trino-main as a dependency because we had subdependency issues with duplicate classes with both same and different versions.
