A guide to designing CockroachDB applications that store and process data across multiple geographic regions.

In plain words
What is it for?
Use it to compare active-active and active-passive setups, choose regional table patterns, configure data placement, and validate multi-region demos.
Why use it?
It helps you choose how reads and writes should be distributed while managing local response times, cross-region delays, and consistency trade-offs.

About the project

CockroachDB Plugin for Cursor connects the Cursor coding agent to CockroachDB clusters for database work such as exploring schemas, writing SQL, debugging queries, and managing distributed clusters. It supports self-hosted and CockroachDB Cloud connections, and its catalogue add-ons provide database-focused agents, skills, rules, and instructions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

designing-multi-region-applications scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Designing Multi-Region Applications

Guides developers through selecting the right multi-region pattern for their CockroachDB application and implementing it with proper validation. Covers the decision model for choosing between regular regional tables, REGIONAL BY ROW, GLOBAL tables, and manual geo-partitioning, plus a hands-on demo framework for comparing approaches.

Complement to other skills: For transaction design patterns, see designing-application-transactions. For SQL syntax and schema design, see cockroachdb-sql.

When to Use This Skill

  • Deciding how to model multi-region read/write behavior in CockroachDB
  • Choosing between active-active and active-passive architectures
  • Evaluating REGIONAL BY ROW vs manual geo-partitioning
  • Understanding GLOBAL table behavior and trade-offs
  • Designing for local reads and writes in multiple regions
  • Building or presenting a multi-region demo or workshop
  • Validating leaseholder placement and zone configurations
  • Optimizing cross-region transaction latency

Do not use this skill when the question is only about SQL syntax, indexing, or generic schema design with no multi-region decision involved.

Prerequisites

  • Understanding of CockroachDB range architecture and leaseholder concepts
  • A multi-region cluster with nodes started using --locality=region=...,zone=... matching the regions used in the examples below. Without matching localities the DDL errors with region "..." does not exist and constraints like +region=... match no nodes. Quickest path locally: 
    # 9-node demo with three regions, three AZs each — note --no-example-database
cockroach demo --no-example-database --nodes=9 \
  --demo-locality=region=NA-NE,az=1:region=NA-NE,az=2:region=NA-NE,az=3:region=NA-MW,az=1:region=NA-MW,az=2:region=NA-MW,az=3:region=EU-DE,az=1:region=EU-DE,az=2:region=EU-DE,az=3
    For long-running clusters, see setting-up-local-cluster and add --locality=region=...,zone=... to each cockroach start invocation.
  • Knowledge of application write patterns (single-region vs multi-region)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
