This duplication occurs because each Android module generates its own BuildConfig file, and productFlavors need to be defined separately in each module to maintain compile-time safety. The question is whether there is a recommended … Read more
Summary This postmortem analyzes the architectural trade-offs in database sharding and proxy-layer query routing. The central issue is managing cross-shard joins with strict latency requirements. We examine whether sharding is worth the complexity for high-scale systems and evaluate strategies like in-proxy hash joins and denormalization. The key takeaway is that sharding introduces unavoidable operational complexity, … Read more
