DVC runs on top of any Git repository and is compatible with any standard Git server or provider (Github, Gitlab, etc). Data file contents can be shared by network-accessible storage or any supported cloud solution. DVC offers all the advantages of a distributed version control system — lock-free, local branching, and versioning.
Use S3, GCP, SSH, SFTP, rsync or any network-attached storage to store data. The list of supported protocols is constantly expanding.
The single 'dvc repro' command reproduces experiments end-to-end. DVC guarantees reproducibility by consistently maintaining a combination of input data, configuration, and the code that was initially used to run an experiment.
Low friction branching
DVC fully supports instantaneous Git branching, even with large files. Branches beautifully reflect the non-linear structure and highly iterative nature of a ML process. Data is not duplicated — one file version can belong to dozens of experiments. Create as many experiments as you want, instantaneously switch back and forth, and save a history of all attempts.
Metrics are first-class citizens in DVC. DVC includes a command to list all branches, along with metric values, to track the progress or pick the best version.
ML pipeline framework
DVC has a built-in way to connect ML steps into a DAG and run the full pipeline end-to-end. DVC handles caching of intermediate results and does not run a step again if input data or code are the same.
Language- & framework-agnostic
No matter which programming language or libraries are in use or how code is structured, reproducibility and pipelines are based on input and output files. Python, R, Julia, Scala Spark, custom binary, Notebooks, flatfiles/TensorFlow, PyTorch, etc. are all supported.
HDFS, Hive & Apache Spark
Include Spark and Hive jobs in the DVC data versioning cycle along with local ML modeling steps or manage Spark and Hive jobs with DVC end-to-end. Drastically decrease a feedback loop by decomposing a heavy cluster job into smaller DVC pipeline steps. Iterate on the steps independently with respect to dependencies.
Bad ideas can sometimes bring more information to colleagues than the the successful ones. Retaining knowledge of failed attempts can save time in the future. DVC is built to track everything in a reproducible and easily accessible way.
