Every growing system hits the database wall. The patterns are well-understood; choosing the right one for your growth shape separates clean scale-up from rewrite.
Vertical First
Modern cloud DBs with 128 vCPUs and 1 TB RAM carry most businesses further than expected. Vertical is cheaper than sharding engineering cost.
Read Replicas Are The First Real Step
Route analytics and non-critical reads to replicas; keep writes and consistency-sensitive reads on primary. Design for replication lag.
Partition Before You Shard
Partitioned indexes are smaller, vacuum faster, dropping old data is free. Only when one partition exceeds one machine do you actually need sharding.
CQRS When Reads/Writes Diverge
Splits write model from read model, usually with different storage. Shines for dashboards and AI data access.
Who This Is For
- CTOs and engineering leaders scaling production systems
- Senior engineers making architecture decisions that compound
- Teams refactoring legacy code under real delivery pressure
Common Mistakes
- Optimizing for theoretical scale before measured demand
- Adding abstraction layers that pay off only in edge cases
- Rewriting instead of refactoring incrementally
Business Impact
- Lower maintenance cost across the lifetime of the system
- Faster feature velocity with fewer production regressions
- Predictable delivery that compounds into engineering trust
Frequently Asked Questions
When move off Postgres?
Rarely before 10 TB or tens of thousands of writes/sec. Postgres is extraordinary and well-tooled.
NoSQL or relational?
Start relational. Modern Postgres handles JSON well; document flexibility alone is not compelling.
What about caching?
Redis in front of Postgres is high-leverage. Start with short TTLs, tighten as you measure.
