Database decisions outlive most code. This post covers relational vs. document vs. key-value vs. time-series vs. graph databases, polyglot persistence, sharding vs. replication, schema evolution, and the decision framework senior engineers use to pick the right store for the job.
Master distributed systems consistency guarantees. Explore ACID vs BASE, CAP theorem nuances, 2PC limitations, consensus algorithms, and when to accept inconsistency. Covers Raft, Paxos, CRDTs, and real-world trade-offs senior engineers face.
A practical decision framework for choosing between REST, GraphQL, and gRPC. Covers HTTP semantics, N+1 problems, schema enforcement, streaming, API versioning, rate limiting, and gateway patterns — with real trade-offs senior engineers face.
Master the art of defining service boundaries using domain-driven design principles. Explore event-driven architecture, async patterns, saga implementations, and how to decouple services while maintaining consistency and system observability.
A pragmatic analysis of monolith and microservices architectures. Explores deployment models, team scaling, operational complexity, and the actual costs of distributed systems for senior engineers making architectural decisions.
