# Welcome to Yuki

Yuki is a **data cloud optimization platform** that helps organizations reduce Snowflake costs and improve performance - **without any code changes or manual tuning**.\
It works by analyzing **metadata**, which means setup is safe, lightweight, and requires zero engineering effort.

Yuki is officially available on the **Snowflake Marketplace**, allowing teams to connect in minutes and start optimizing immediately.

***

### What Yuki Does

Modern data teams spend significant time and budget managing Snowflake compute.\
Yuki automates this optimization layer and integrates directly with Snowflake using **metadata APIs** - with no query interception and no access to your data.

It continuously:

* Monitors **query and warehouse metadata** to understand workload behavior - including query  history, execution time, and warehouse utilization
* Detects inefficiencies in **warehouse sizing**, **runtime**, and **credit consumption**
* Based on observed workload patterns, **automatically adjusts warehouse sizes and routes queries** to the most suitable compute resources - ensuring optimal performance and cost efficiency without user intervention

**The result:** lower spend, faster queries, and full visibility into compute usage.

Because Yuki operates purely on metadata, there’s:

* **No code modification**
* **No change to user behavior or query paths**
* **No data exfiltration risk**

### Deployment Types

Yuki can be deployed in two modes depending on your data residency and security requirements:

#### **1. Full SaaS**

Yuki hosts and manages the full optimization layer. You simply connect your Snowflake account using a service user and key-pair authentication.\
No infrastructure setup, no maintenance - you start optimizing within minutes.

#### **2. Hybrid Deployment**

For organizations that require processing within their own VPC or Business Critical Snowflake accounts.\
You deploy the **Yuki Proxy** inside your environment via:

* **Helm Chart**
* **Terraform**

\
In this setup, Yuki runs entirely inside your environment, forwarding only optimization metadata over HTTPS to the Yuki Engine.

### Metadata-Only by Design

Yuki never reads or copies customer data - only **system metadata** such as:

* Query IDs, timestamps, and runtime
* Warehouse sizes and credit usage
* Execution statistics

This ensures compliance with strict privacy standards (SOC 2 Type II, GDPR) while maintaining full visibility into performance and spend.

***

### Security and Isolation

* **No access to data** - Yuki only reads Snowflake metadata tables (`ACCOUNT_USAGE`, `INFORMATION_SCHEMA`, etc.).
* **Secure connection** - authentication is done via Snowflake service user and key-pair.
* **Optional Hybrid mode** - run Yuki Proxy inside your environment to keep all metadata local.
