SchemaPlan

classin packageklyn.data

public class SchemaPlan:

SchemaPlan

Immutable, provider-neutral plan that reconciles mappings and physical data.

A plan owns no connection, credentials or mutable provider session. Apply it through the SchemaManager that produced it so lifecycle and stale-plan checks remain centralized.

plan = factory.schema.diff()
print(plan.preview)
factory.schema.apply(plan)
