Performing Cluster Maintenance
Manages planned cluster maintenance across all deployment tiers. For Self-Hosted, this means draining and restarting individual nodes. For Advanced/BYOC, this means configuring and managing maintenance windows for CRL-applied patches. For Standard and Basic, maintenance is fully managed with no customer action required.
When to Use This Skill
- Planning OS patching, hardware changes, or configuration updates (Self-Hosted)
- Configuring or modifying a maintenance window (Advanced, BYOC)
- Setting patch deferral policies (Advanced, BYOC)
- Monitoring during a CRL-managed maintenance event (Advanced, BYOC)
- Running pre-maintenance validation checks (Self-Hosted, Advanced, BYOC)
- Understanding how maintenance affects your application (all tiers)
- Preparing applications for maintenance events (all tiers)
For permanent node removal: Use managing-cluster-capacity. For pre-maintenance health check: Use reviewing-cluster-health. For version upgrades: Use upgrading-cluster-version.

cockroachdb-sql
Use when writing, generating, or optimizing SQL for CockroachDB, designing CockroachDB schemas, or when the user asks about CockroachDB-specific SQL patterns, type mappings, and distributed database best practices. Also use when encountering CockroachDB anti-patterns like missing primary keys, sequential ID hotspots, or incorrect type usage.
36analyzing-range-distribution
Analyzes CockroachDB range distribution across tables and indexes using SHOW RANGES to identify range count, size patterns, leaseholder placement, and replication health. Use when investigating hotspots, uneven data distribution, range fragmentation, or validating zone configuration effects without DB Console access.
32auditing-table-statistics
Audits optimizer table statistics for staleness, missing coverage, and data quality issues using SHOW STATISTICS. Use when diagnosing poor query performance, unexpected plan changes, or after bulk data changes to identify stale statistics requiring refresh via CREATE STATISTICS.
30monitoring-background-jobs
Monitors CockroachDB background job health by identifying failed, paused, and long-running jobs using SHOW JOBS and SHOW AUTOMATIC JOBS. Surfaces schema changes, backups/restores, automatic statistics collection, and SQL stats compaction jobs without DB Console access. Use when investigating schema change delays, failed backups, or automatic job issues.
29managing-cluster-settings
Reviews, audits, and modifies CockroachDB cluster settings. Self-Hosted has full control over all settings and start flags. Advanced/BYOC can modify most SQL-level settings but infrastructure settings are managed by CRL. Standard has limited settings access — session variables are the primary tuning mechanism. Basic has minimal settings — use session variables and Cloud Console. Use when auditing configuration, tuning performance, or troubleshooting settings-related issues.
29benchmarking-transaction-patterns
Guides benchmarking and comparing explicit multi-statement transactions versus single-statement CTE transactions in CockroachDB, with fair test methodology, contention analysis, and performance interpretation. Use when comparing transaction formulations, benchmarking CockroachDB workloads under contention, investigating retry pressure, or deciding whether to rewrite multi-step application flows into single SQL statements.
