# Cloud Sync

**Cloud Sync** lets you automatically synchronize customer profile data from your **data warehouse** (BigQuery, Snowflake, Databricks, etc.) or **relational databases** (MySQL, PostgreSQL) into **Batch** without building custom pipelines or relying on third-party tools.

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