Azure Cosmos DB Skill

This skill provides expert guidance for Azure Cosmos DB. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

• Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
• Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Architecture & Design Patterns	L209-L251	Architectural patterns for Cosmos DB and PostgreSQL: multitenancy, sharding, HA/DR, change feed, HTAP, real-time analytics, and AI/LLM agents, memory, vectors, and semantic caching.
Limits & Quotas	L252-L292	Limits, quotas, and behaviors for Cosmos DB (all APIs, backup, autoscale, serverless, free tier, fleets) and Cosmos DB for PostgreSQL, including RUs, storage, partitions, and performance.
Security	L293-L359	Securing Cosmos DB and related services: identity/RBAC, keys and encryption, network isolation (VNet, Private Link, firewalls), TLS, auditing, policies, and data‑level protections.
Configuration	L360-L485	Configuring Cosmos DB and related services: throughput, indexing, TTL, backup/restore, global distribution, monitoring, emulators, SDK tuning, and deployment via Bicep/ARM/Terraform across all APIs.
Integrations & Coding Patterns	integrations.md	SDK patterns, bulk ops, change feed, vector search, and integrations (Kafka, Spark, Functions, BI, AI/RAG) plus migration guides for Cosmos DB APIs (NoSQL, Mongo, Cassandra, PostgreSQL, DocumentDB).
Deployment	deployment.md	Deploying and managing Cosmos DB and Azure DocumentDB: ARM/Bicep/Terraform templates, CI/CD, scaling, backup/restore, upgrades, maintenance, and start/stop operations for various APIs.
