What is Hangar?
Hangar is based off the belief that too much time is spent collecting, managing,
and creating home-brewed version control systems for data. At it’s core Hangar
is designed to solve many of the same problems faced by traditional code version
control system (ie. Git), just adapted for numerical data:
Time travel through the historical evolution of a dataset.
Zero-cost Branching to enable exploratory analysis and collaboration
Cheap Merging to build datasets over time (with multiple collaborators)
Completely abstracted organization and management of data files on disk
Ability to only retrieve a small portion of the data (as needed) while still
maintaining complete historical record
Ability to push and pull changes directly to collaborators or a central server
(ie a truly distributed version control system)
The ability of version control systems to perform these tasks for codebases is
largely taken for granted by almost every developer today; However, we are
in-fact standing on the shoulders of giants, with decades of engineering which
has resulted in these phenomenally useful tools. Now that a new era of
“Data-Defined software” is taking hold, we find there is a strong need for
analogous version control systems which are designed to handle numerical data at
large scale… Welcome to Hangar!
