Database Replication Advisorv1.0.1

An online retailer experiences high read traffic for product browsing and search but lower write traffic for orders and inventory updates. They run PostgreSQL with a primary and two async replicas, and need to monitor replica lag to avoid showing stale inventory or prices to customers.

A B2B SaaS platform serves customers across North America and Europe, requiring low-latency reads and disaster recovery. The team must evaluate cross-region replication lag, failover readiness, and split-brain risk when promoting a replica during a regional outage.

A fintech company runs a transaction ledger where any committed write must survive a database failover. They are considering synchronous replication but need to understand the tradeoff between RPO=0 and increased write latency or reduced availability.

An IoT platform ingests millions of sensor readings per second and must replicate data to analytics replicas for near-real-time dashboards. The team needs to measure replication lag and ensure the primary can sustain WAL generation without overwhelming standby replay.

A media company uses multi-leader replication across regions so editors can publish content locally without cross-region write latency. They need to detect replica drift and resolve conflicts before readers see inconsistent articles.

A cloud provider offers a fully managed PostgreSQL or MySQL service with automated replication setup, lag monitoring, and failover orchestration. Customers pay a monthly subscription based on instance size and replica count.

A standalone monitoring platform connects to customers' databases to continuously measure replication lag, detect conflicts, and alert on failover readiness. It provides dashboards and recommendations for topology improvements.

Database experts offer one-time or ongoing consulting to assess replication topology, run failover drills, and recommend CAP-aligned strategies. Deliverables include health reports and implementation guidance.
