# spicedb

So... a thought experiment to see if I've grokked this. Say I, a resource owner, make an update to the resource. The app puts a zedtoken on the resource while sending a spicedb update to some out-of-band process via SQS or Rabbit or similar. Then the queue gets congested and spicedb relations lag the application DB by 30 minutes while the infrastructure team scrambles to fix the congestion. In the meantime, a user tries to access the resource. Presumably (?) they grab the zedtoken off the resource and send it with their spicedb permissions check. The data in SpiceDB lags the app data so the zedtoken is invalid (somehow). SpiceDB responds with... what?
