# Overview

> Data delivery straight to your data lake for privacy and control.

export const chainCount = '85+';

Allium handles and maintains bulk data delivery and the full lifecycle management of data delivery, including often-overlooked complexities:

* **Bulk delivery** - Deliver 100s of TBs of data into any destination in days, avoiding custom scripts
* **Seamless schema updates & migrations** - Leveraging Iceberg table format with clearly-defined SOPs for backward compatibility
