Schema Patches — batch, review, and publish schema changes together

Schema Patches are the new way to make schema changes in Lytics. Instead of editing fields and mappings directly into a shared draft, every change now goes through a patch — a named changeset where you can group related changes, review themas a complete diff, and publish them all at once. Once the Patches feature is activated for your account, all schema changes will go through this new publishing flow.

What's new

• Group related changes to fields, mappings, and identity key ranks into a single changeset, then review and publish them together — ideal when onboarding a new data source or reorganizing identity resolution, where the changes only make sense as a unit.
• See exactly what will change before anything goes live: every modified field and mapping comes with a property-level diff showing before/after values.
• Nothing reaches your live schema without an explicit review-and-apply step, so changes can't slip in unreviewed.
• Name and describe each changeset so it's clear who changed what and why — useful when multiple people are working on the schema.
• Undo an individual change inside a patch without discarding the rest.

How it works

Applying a patch publishes a new schema version containing all of its changes. If something goes wrong, revert to a previous version from your schema version history. Most teams will work with patches through the Visual Schema Editor; the underlying concept and API are documented separately.
