Customize your designs
The whole shtick of SpacetimeDB is that the performance and availability of both your application and your database is 100% dominated by short segments of user code which cannot perform any operations with side effects or stalls, because they’re compiled to WebAssembly and executed by a virtual machine inside a critical section that serializes all writes and reads to the storage backend of your application. The absence of side effects or stalls cannot be enforced by the type system, and is dependent on the particular WASM bytecode that is generated by a JIT compiler at runtime. Any mistake inside these critical sections, any operation that could cause them to stall under load, is probably only going to be seen in production, and is going to degrade the performance of your whole application — most likely to the point of causing an availability issue.
