Schema Registry

This step appears as Schema Migration in the wizard sidebar. It is optional. When enabled, the suite migrates schemas alongside topic data, ensuring that the destination cluster has the correct schema definitions in place for producers and consumers.

Enabling Schema Migration

Toggle the Enable/Select switch to ON to activate schema migration configuration. When disabled, the wizard skips schema-related steps entirely.

Selecting Registries

Once enabled, select the source and destination schema registries:

Field	Description
Source Schema Registry	The registry containing the schemas to migrate. Select from saved configurations or click Add New to register a new registry inline.
Destination Schema Registry	The target registry where schemas will be replicated. Select from saved configurations or click Add New to register a new registry inline.

Duplicate Registry Validation

The suite validates that the source and destination registries are not the same. If you select the same registry for both, an error is displayed and you must correct the selection before proceeding.

Caution

WarpStream Schema Linking supports only one-way replication. The destination Schema Registry must be initially empty to preserve schema IDs. If the destination already contains schemas, ID conflicts may occur and schema linking will fail.
