Hasura to Denodo Connectivity required (data connector simillar to power BI to Denodo connection)

### Is your proposal related to a problem?

### Describe the solution you'd like

### We are developing Denodo & Java Service for GraphQL API creation. As Hasura supports out of the box GRaphQL/Rest API with less coding we prefer to use the Hasura for API creation (but we conn't connect db directly)

The issue names no files, tests, or entry points. Start by clarifying the required Denodo connectivity, supported deployment path, and expected GraphQL behavior, then review Hasura's existing data-connector approach. Done means the agreed Denodo integration works for the required data access and API creation scenarios.
