## About

# Couchbase Capella Analytics

A skill for *designing and using* Couchbase Capella Analytics — the standalone columnar analytics database product on Capella.

> **Naming:** Couchbase formally rebranded **Capella Columnar** to **Capella Analytics**. This skill uses "Capella Analytics" for the product. The lowercase word "columnar" still appears where it describes the underlying *storage format* (columnar storage), and some API/endpoint names retain "Columnar" (e.g. Columnar Analytics Cluster) — those are left as-is where they are literal identifiers.

Distinct from the `cb-analytics-*` skills, which cover the **Analytics Service** embedded within Couchbase Server / Capella operational clusters. These are different products:

| | Analytics Service (embedded) | Capella Analytics (standalone) |
|---|---|---|
| **What it is** | Analytics service co-located with an operational cluster | Standalone columnar database, separate instance |
| **Where it runs** | On Analytics nodes of an operational cluster | Separate Capella Analytics instance on Capella |
| **Data ingestion** | DCP-based streaming from the operational cluster | Links to Capella operational cluster, S3, or external sources |
| **Storage** | Row-oriented (same as operational) | True columnar storage |
| **Best for** | Ad-hoc analytics alongside operational workloads | OLAP, BI tools, large analytical queries |
| **Skills** | `cb-analytics-*` | This skill |

## When this skill applies

- "What's Capella Analytics (Capella Columnar)?"
- "Should I use standalone Capella Analytics or the embedded Analytics Service?"
- "How do I connect Capella Analytics to my operational Capella cluster?"
- "How do I connect a BI tool (Tableau, Power BI, Looker) to Couchbase?"
- "How do I query JSON data in Capella Analytics?"
- "What's the difference between Analytics collections and operational collections?"

## Pick the right reference

| Question | Read |
|---|---|
| "Capella Analytics architecture, when to use it vs the embedded Analytics Service" | `references/architecture.md` |
| "Connecting data sources, querying, BI tool integration" | `references/usage.md` |

## Core principle: Capella Analytics is for OLAP, not OLTP

Capella Analytics is optimized for analytical queries — large scans, aggregations, GROUP BY, window functions, JOINs across large datasets. It is not a replacement for the operational cluster. Transactional writes (your application's reads/writes) still go to the operational cluster. Capella Analytics receives data via links and stores it in columnar format for efficient analytical access.
