Transactions & ACID
Isolation models and optimistic paths.
Replication & availability
Leaders, followers, and consistency expectations.
Monitoring & observability
Metrics, logs, health checks, and SLO thinking.
Performance tuning
Profiling, benchmarks, and real bottlenecks.
Deployment & configuration
Shipping, backups, and operations.
Security & hardening
Threat model basics and safer defaults.
Capstone & beyond
Integrate, document, and extend your engine.
Common Inquiries
How much Go do I need?
You should be comfortable writing non-trivial Go and using the standard library. We do not teach the language from zero.
Is this only theory?
No—you implement components (WAL, LSM pieces, server, client) in a progression that mirrors how engines are actually built.
Will this get me a job?
It is a serious portfolio piece: you can explain trade-offs, show benchmarks, and discuss failure modes like in real interviews.
