@dikla - The Databricks Genie API currently only documents the high‑level schema for spaces (via GET /spaces/{id}), but the join_specs, sql_snippets, and measures objects are not fully supported for persistence when passed directly in POST /spaces. That’s why your join_specs disappear — the API ignores them unless they conform to the internal schema used by Genie’s space builder.

Current Limitiations: 

• Joins: Must be inferred by Genie or added manually in the UI; API does not persist them.

• Measures / SQL snippets: Same limitation — they can be read via GET /spaces/{id} but not reliably written via POST.
