Best for

  • Designing PostgreSQL streaming replication topology for 50TB SaaS database across 3 AWS regions
  • Optimizing MySQL master-slave lag for real-time inventory system with <100ms RPO requirement
  • Migrating from synchronous to asynchronous replication to reduce write latency by 40%
  • Setting up cascading replica hierarchy to handle 10,000 read queries/second
  • Implementing automated failover with Patroni for zero-downtime PostgreSQL cluster

What you'll get

  • Multi-region replication architecture diagram with primary-replica relationships, network latency considerations, and specific PostgreSQL WAL shipping configuration
  • Detailed failover procedure documentation with Patroni configuration, health check parameters, and rollback scenarios
  • Performance benchmark comparison of synchronous vs semi-synchronous replication with specific latency and throughput metrics
Not designed for ↓
  • ×Application-level database schema design or table structure optimization
  • ×SQL query performance tuning or index optimization strategies
  • ×Database backup and restore procedures without replication context
  • ×NoSQL database replication (focuses on relational systems)
Expects

Database workload characteristics, performance requirements, geographic constraints, and specific RPO/RTO targets with current infrastructure details.

Returns

Detailed replication topology design with configuration parameters, monitoring setup, failover procedures, and operational runbooks.
