[1:21] What is the dual-write problem [11:50] How to solve it ? [13:33] Consistency Checking [19:38] Eventual Consistency Patterns [33:19] Durable Execution Environments [42:29] Transaction Outbox Pattern [57:42] How do you choose? The dual-write problem presents itself in all distributed systems. A system that uses SpiceDB for authorization and also has an application database (read: most of them) is a distributed system. Working around the dual-write problem typically requires a non-trivial amount of work and this stream will discuss the different approaches to do so.
