That is probably very straightforward to write. The nearest thing that currently exists is CloneSchema, which I would describe as a ‘caching proxy’. You could copy it and make each table return a single row of all ones. Or I would be inclined to return the ‘zero’ value for each datatype (0 for ints, false for BOOLEAN, 0.0 for floats, empty string, DATE ‘1970-1-1’, etc.).
Feel free to create a JIRA case sketching out the requirement, even if you don’t currently have time to implement it.
