The Brief
What you'll do, and what you'll demonstrate.
Which of CockroachDB, TiDB, or Spanner best fits a real-time, multi-region inventory store, and why — grounded in prototype evidence rather than vendor claims?
This is not a research exercise. It is the work a researcher does to produce findings that withstand scrutiny. That distinction matters to every hiring manager who has seen candidates summarize papers and none who have produced original findings under expert review.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Distinguish NewSQL transaction protocols (CockroachDB's Spanner-inspired multi-active design, TiDB's multi-Raft over TiKV, Spanner's TrueTime) at the protocol level rather than the feature-list level
- Reason about isolation, consistency, and failover trade-offs under geo-distribution and network partition
- Translate concrete application transactions into a workload that exposes a database's real behavior
- Build a weighted decision matrix that maps system properties to stated business requirements
- Communicate an evidence-backed architecture recommendation to a senior technical audience

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Distributed Systems Architect
This challenge mirrors the core of the role: evaluating competing distributed databases at the protocol level and recommending one against real business constraints, bridging architecture comparison with deep distributed-database and Raft consensus understanding.

Database Reliability Engineer
Prototyping contentious transactions and probing failover semantics is exactly the diligence a DRE applies before adopting a NewSQL store, connecting transaction-protocol reasoning with hands-on NewSQL operational evaluation.

- transaction-protocols
- newsql
- distributed-databases
Principal Platform Engineer
Reaching and defending a platform-defining database choice from evidence — and communicating it to senior stakeholders — is the judgment a principal engineer is paid for, anchored in Spanner-grade architecture knowledge and rigorous comparison.
