A two-dimensional filesystem build and distribution framework for containers.

An extension of the container layered structure with a new two-dimensional filesystem layer type, specifically designed for efficient handling of large data.

2DFS is composed of:

• A new container layer type: 2dfs.field
• A 2DFS builder, to build a 2dfs.field on top of a regular OCI container image
• A 2DFS Registry, to host and distribute 2dfs and OCI compliant images.
• A 2DFS flattening technique, allowing 2DFS images to be pertitioned on demand and distributed as traditional OCI images for ANY runtime.

• 2DFS Builder: A tool to build 2DFS images from OCI images, with a focus on large data handling. Build performance up to 50x faster than Docker for large data.
• 2DFS Registry: A registry to host and distribute 2DFS images. It allows image partitioning via semantic tags, enabling on-demand retrieval of only the required data. This is particularly useful for large datasets, AI model partitions, drivers, and other large data files.
• 2DFS Flattening: A technique to flatten 2DFS images into OCI images, allowing them to be distributed as traditional OCI images for any runtime. This enables the use of 2DFS images in your pre-existing infrastructure, without the need for any changes.
