This comprehensive guide provides advanced techniques to diagnose and significantly boost ClickHouse query performance. It covers analyzing slow queries using system tables, optimizing ORDER BY keys, implementing data skipping indexes (Bloom, Set, MinMax), utilizing projections for pre-aggregation, and fine-tuning server settings and materialized views. Essential for high-volume OLAP environments.

This comprehensive checklist guides users through critical operational readiness steps for a ClickHouse production deployment. It covers server tuning (config.xml), schema design best practices, robust backup strategies (S3), detailed monitoring setup (Prometheus/Grafana), security hardening, and application integration verification. Use this document before go-live, during major upgrades, or when auditing production systems to ensure maximum stability and performance.

Provides a comprehensive, production-ready reference architecture for building advanced analytics platforms powered by ClickHouse. It details everything from project layout (TypeScript/Node.js structure) and data ingestion pipelines (Kafka, Webhooks) to the optimal 3-layer schema design (Raw, Hourly, Daily) and multi-tenancy patterns, ensuring scalable and efficient OLAP query performance.

This guide provides production-ready patterns for using the @clickhouse/client library in Node.js. It covers critical, real-world scenarios such as safe typed queries, streaming large data inserts (with backpressure handling), robust batch operations with retries, and streaming SELECT queries for low memory consumption. It also includes best practices for comprehensive error handling and connection lifecycle management, ensuring stable and scalable ClickHouse integrations for data pipelines.

This comprehensive guide details best practices for securing a ClickHouse deployment. It covers essential security measures including role-based access control (RBAC) for granular user permissions, implementing row-level security for multi-tenancy, configuring network IP restrictions, enabling TLS encryption, and setting up detailed audit logging. Use this when hardening a production ClickHouse instance or enforcing strict data governance.

A comprehensive, step-by-step guide for safely upgrading ClickHouse server versions and the associated Node.js client SDK. This guide covers pre-upgrade checks, reviewing major breaking changes, updating client code (e.g., 'host' to 'url'), performing server backups and updates, and implementing full validation and rollback procedures.

Automates the integration of ClickUp API within Continuous Integration/Continuous Deployment (CI/CD) pipelines using GitHub Actions. This skill allows users to run comprehensive unit and integration tests against the ClickUp API v2, and critically, enables syncing the final deployment status (e.g., 'deployed') back to the corresponding ClickUp task, ensuring task tracking is always aligned with development progress.

This comprehensive guide serves as a reference for diagnosing and resolving common errors when interacting with the ClickUp API v2. It covers critical HTTP status codes (400, 401, 403, 404, 429, 500) and specific OAuth error codes (ECODEs). Use this resource when debugging failed API requests, troubleshooting authentication issues, or implementing robust error handling logic in your application.

Manage the entire ClickUp organizational hierarchy programmatically, including spaces, folders, lists, views, and tags. This tool is essential for scaffolding complex project structures, automating resource organization, and maintaining consistency across large-scale workflows using the ClickUp API v2.

This skill provides comprehensive handling for sensitive data extracted from the ClickUp API. It includes automated PII detection (emails, phone numbers, SSN), data redaction for secure logging, and mechanisms to ensure GDPR/CCPA compliance through structured data exports. Furthermore, it enforces data retention policies, managing data lifecycle from collection to secure deletion.

This guide provides a comprehensive walkthrough for starting with the ClickUp API v2. It details the platform's core data hierarchy (Workspace > Space > Folder > List > Task) and demonstrates the fundamental API calls required for integration setup. Users will learn how to list workspaces, retrieve spaces, and successfully create a new task using both cURL and TypeScript examples. It is ideal for developers beginning a new ClickUp integration or requiring basic API testing.

A comprehensive runbook for managing ClickUp API v2 integration failures and outages. It guides users through rapid incident triage, diagnosis based on specific error codes (401, 429, 500), and implementing advanced mitigation techniques like circuit breakers and graceful degradation. This ensures systematic and efficient service recovery.
