Who coordinates access to the same record?
Designing a table around queries addresses how data is laid out. Routing operations to one process addresses how simultaneous work on a record is coordinated.
Read on through a shared source
What must happen before work can run in parallel? →Follow the point where workers have to wait. Adding workers helps only after the serial activity that feeds them can keep up.How far can one bottleneck spread? →Process isolation contains certain runtime failures. Decoupling services can contain a capacity problem. Identify what is still shared before relying on either boundary.Can healthy work continue when one component fails? →Process isolation and decoupling services address failure at different scales. Both limit propagation, but shared resources can still carry failure across a boundary.
