14 · Versioning your data

Status: stub.

Icechunk adds transactional, git-like versioning to Zarr without changing the data model you just learned. This closing chapter places it relative to everything else.

What this chapter will cover

• The problem: coordinated updates and history over array data in the cloud.
• How Icechunk acts as a store with snapshots, commits, and time travel — so the Part I model is unchanged; only the store gains superpowers.
• When you need it and when a plain store is enough.
• Pointers onward: Icechunk docs and the zarr-intro sections that demo it.
