Our review
Pros
  • Versions arbitrarily large files with branching and rollback
  • Captures provenance and supports reproducible command execution
  • Connects datasets with GitHub, Figshare, Dropbox, Amazon S3, and OSF
  • Git-like commits, branches, tags, hashes, and historical access
  • Atomic transactions across multiple tables
  • Integrates with Iceberg, Spark, Flink, Hive, and Trino
Cons
  • Uses a self-hosted deployment model
  • Storage depends on user-configured siblings or special remotes
  • The workflow centers on Git and git-annex dataset management
  • Focused on table metadata rather than broad data-asset versioning
  • Self-hosted deployment requires infrastructure management
  • Requires a bring-your-own version-store backend
