Tanstack DB with Tanstack Table

TanStack Table + DB: Best pattern for EAV schema with dynamic columns? Building an Airtable clone where users create custom tables with dynamic columns. Schema: tables → columns → rows → cells (EAV pattern)
Problem: TanStack Table needs flat data, but DB is EAV Current approach: - Server pivots EAV → Flat (getTableFlat()) - Client uses useSuspenseQuery (React Query) for reads - Use useLiveQuery + Collections for column/row mutations (optimistic) - Cell edits = direct mutation + full refetch (200-500ms lag) Question: Should I: 1. Keep server-side pivot + accept lag with UX polish (toasts, loading)? 2. Migrate to client-side pivot with useLiveQuery (complex but optimistic)? 3. Use a different schema design entirely? Is there a TanStack-recommended pattern for dynamic columns + EAV → flat transformation? Stack: TanStack Start/Table/DB/Query, PostgreSQL, Drizzle ORM
