David Overton 26dfa3e718 Replace TableObjectType, etc. with the corresponding Logical Model types ... ## Description This is the first step in making use of Logical Models with document databases such as MongoDB. As part of schema introspection, a data connector agent can supply a set of custom types that can be used to describe the schema for columns within the tables of the database (or _fields_ within a _document collection_ in MongoDB terminology). Previously, we were storing these custom types as `TableObjectType`s within the `TableCoreInfo` for each table. In this PR we - replace the `TableObjectTypes` with `LogicalModel` types - store these directly within the `DBObjectsIntrospection` instead of within the `TableCoreInfo` for each table. (The custom types are shared at the source level so there was no reason to have a separate set of types for each table.) - When building the `SourceInfo`, we combine the `LogicalModel`s from `DBObjectsIntrospection` with `LogicalModel`s from the user's metadata to create the set of `LogicalModels` in the `SourceInfo` within the `SchemaCache`. I.e. we combine the set of types obtained by database introspection with the set of types specified by the user in the metadata. If two types have the same name, we use the type defined in the metadata. ## Limitations and future work - Provide a way for the user to associate a meta-data defined `LogicalModel` with a table instead of requiring one to be provided by DB introspection - Provide a way for the user to edit the `LogicalModel` types provided by introspection and add them to the metadata. - Allow a `LogicalModel` object type to describe and entire table rather than just individual columns. - Better handling for "unknown" types, e.g. if the type of a collection (or part of a collection) is unknown we should treat it as a JSON scalar value. This may also involve adding an `_everything` field which returns the full document as a JSON scalar.
