Caching
Caching strategies and implementation
@tank/system-design
by tankpkg
Practical system design for production distributed systems. Covers scalability patterns (load balancing, horizontal scaling, CDN, auto-scaling), data layer design (database selection, replication, sharding, consistency models, CAP theorem applied), caching strategies (cache-aside, write-through, invalidation, stampede prevention), messaging and async patterns (queues vs streams, event-driven architecture, CQRS, saga pattern, delivery guarantees), reliability (circuit breakers, bulkheads, retries, rate limiting, timeouts, chaos engineering), service architecture (monolith vs microservices, API gateway, service mesh, distributed transactions), and capacity planning (back-of-envelope estimation, SLOs/SLIs, monitoring, distributed tracing). Synthesizes Kleppmann (Designing Data-Intensive Applications), Vitillo (Understanding Distributed Systems), Newman (Building Microservices), Ford et al. (Software Architecture: The Hard Parts), Nygard (Release It!), Petrov (Database Internals), Richards & Ford (Fundamentals of Software Architecture), and Beyer et al. (Site Reliability Engineering). Trigger phrases: "system design", "distributed systems", "scalability", "load balancing", "horizontal scaling", "vertical scaling", "database sharding", "database replication", "caching strategy", "cache invalidation", "message queue", "event-driven", "Kafka", "RabbitMQ", "pub/sub", "circuit breaker", "rate limiting", "bulkhead", "retry strategy", "microservices", "monolith", "API gateway", "service mesh", "CAP theorem", "eventual consistency", "strong consistency", "CQRS", "event sourcing", "saga pattern", "back-of-envelope", "SLO", "SLI", "capacity planning", "distributed tracing", "back pressure", "cache stampede", "thundering herd", "how should I scale", "which database", "when to use microservices"

developing-google-cloud
by sumik5
Google Cloud development guide covering Cloud Run (architecture, scaling, CI/CD), GCP security (IAM, VPC, KMS, DLP, SCC, Zero Trust, Chronicle), data engineering (BigQuery, Dataflow, data pipelines, governance), network engineering (VPC, load balancing, CDN, Traffic Director), and Memorystore (Redis/Memcached, cache patterns, resilience). MUST load when Dockerfile is detected with google-cloud packages, when cloudbuild.yaml is present, or when working with BigQuery, Dataflow, Dataproc, Cloud Interconnect, or Memorystore. For Docker-specific patterns, use managing-docker instead. For general monitoring design, use designing-monitoring instead. For code-level security (OWASP, CodeGuard), use securing-code instead. For data architecture patterns (CQRS, event sourcing), use architecting-data instead. For AWS development, use developing-aws instead. For serverless security (GCS hacking, Cloud Run abuse), use securing-serverless instead. For application logging, use implementing-logging.
