Compare NewSQL Architectures for a Real-Time Inventory Platform

FreeVerified credential6 weeksExpert

Overview

What this challenge is about.

Study the architecture papers and documentation for CockroachDB (its Spanner-inspired multi-active design), TiDB (Raft + multi-Raft + TiKV + TiDB SQL layer), and Spanner (TrueTime). Compare on: (1) data model and SQL surface, (2) transaction protocol and isolation, (3) geo-distribution strategy, (4) failover semantics, (5) operational properties (backup, upgrade, schema change). Run a small-scale prototype against the inventory team's most contentious 4 transactions on each, just to ground the comparison. Deliver an 18-page architecture-comparison paper, a comparison matrix, the prototype code, and a 45-minute readout for the principal engineer.

The Brief

What you'll do, and what you'll demonstrate.

Produce a deep-architecture comparison of CockroachDB, TiDB, and Spanner for a real-time multi-region inventory platform, grounded in prototype workloads.

Earning criteria — what you'll demonstrate

  • Read distributed-database architecture papers critically
  • Compare transaction protocols across Raft-based and TrueTime-based systems
  • Ground architecture comparisons in real prototype evidence
  • Brief a principal engineer without losing technical nuance
