SpacetimeDB creator sets "not yet" boundaries

SpacetimeDB’s positioning is getting sharper: it can be a huge leverage play for real-time products, but trying to force-fit it into mature Postgres or analytics-heavy stacks will create avoidable pain.

• –This is a healthy signal for developer trust: explicit limits beat “works for everything” marketing.
• –Partial Postgres compatibility means teams with existing SQL tooling and assumptions should treat migration risk as real, not theoretical.
• –The architecture shines when you want state, sync, and backend logic tightly integrated for multiplayer or collaborative apps.
• –For heavy analytical workloads, columnar/distributed data systems remain the pragmatic choice until SpacetimeDB’s compatibility and scale story matures.
