A portable, scalable, and fast AI Data Lakehouse.

DeltaCAT is a portable Multimodal Data Lakehouse powered by Ray. It lets you define and manage fast, scalable, ACID-compliant Multimodal data lakes, and has been used to successfully manage exabyte-scale enterprise data lakes.

It uses the Ray distributed compute framework together with Apache Arrow and Daft to efficiently scale common table management tasks, like petabyte-scale merge-on-read and copy-on-write operations.

DeltaCAT provides four high-level components:

1. Catalog: High-level APIs to create, discover, organize, and manage datasets.
2. Compute: Distributed data management jobs to read, write, and optimize datasets.
3. Storage: In-memory and on-disk multimodal dataset formats.
4. Sync: Synchronize DeltaCAT datasets with other data warehouses and table formats.

Getting Started
