Database Scaling Patterns

Tech Stack

simulate_database_partitioning - Demonstrates PostgreSQL table partitioning strategies
simulate_database_sharding - Demonstrates database sharding across multiple PostgreSQL instances
simulate_read_replicas - Primary + streaming replicas: read scaling, replication lag, read-your-writes
simulate_connection_pooling - PgBouncer multiplexing many clients onto a few PostgreSQL connections
simulate_query_caching - Redis cache-aside with TTL, write-through, and invalidation
simulate_read_write_splitting - Application-level router sending writes to the primary and reads to replicas
simulate_consistent_hashing - Hash ring with virtual nodes: minimal data movement on resize vs modulo sharding
simulate_cqrs - Command Query Responsibility Segregation: normalized write store + denormalized read store via a projector
simulate_automatic_failover - Health-checked failover manager promoting a standby with pg_promote()
simulate_multitenancy_shared_schema - Shared schema multi-tenancy isolated with PostgreSQL Row-Level Security
simulate_event_sourcing - Append-only event log: state reconstruction by replay, snapshots, optimistic concurrency
simulate_newsql - 3-node CockroachDB cluster: distributed ACID transactions, auto-sharding/replication, fault tolerance
simulate_data_tiering - Hot/warm/cold storage tiers via partitioning + tablespaces with age-based migration
