{% hint style="info" %}
Cloud Sync is a priced offering. Reach out to your CSM or Account Manager to learn more.

**Cloud Sync** lets you automatically synchronize customer data from your **data warehouse** ( or **relational databases** into **Batch** without building custom pipelines or relying on third-party tools.

In just a few minutes, your profile data and behavioral events stay up to date in Batch, helping you launch campaigns faster, reduce engineering dependency, and simplify implementation.

### What can you sync?

Cloud Sync supports two destination types:

| Destination                    | What it does                                                                                                                           |
| ------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------- |
| **Batch > Profile attributes** | Updates customer profile attributes (email, plan, country, lifetime value, etc.) in Batch from a table containing one row per profile. |
| **Batch > Profile events**     | Creates behavioral events (purchases, add-to-cart, page views, etc.) in Batch from a table containing one row per event.               |

You select the destination type when creating a sync in the Batch dashboard.

***

### How it works

All Cloud Sync configurations share the same core mechanism:

1. **You prepare a table or view** in your data source that follows the Cloud Sync schema (required columns, naming conventions, type formatting).
2. **You create a sync** in the Batch dashboard by selecting a source, a sync frequency, and a destination type.
3. **Batch runs incremental syncs** on your chosen schedule, fetching only rows that changed since the last run using a `last_updated_at` cursor.

Once enabled, Batch automatically handles batching, retries, and error reporting.
