How to model polymorphic request and response bodies in OpenAPI 3.x using oneOf with a discriminator: a worked Pet/Cat/Dog schema, why the mapping table and required property matter, and the pitfalls that break validators and generators.
Learn how to use Discloud's manifest‑based validation phase to prevent deployment failures by enforcing resource schema compatibility before allocation.
Goal Determine whether Cosmos DB can automatically revert writes that succeed before a schema validation rule change but become invalid after the change, without requiring application‑level compensation. The container‑level JSON schema validation is enforced at write time, and while TransactionalBatch provides atomicity across documents, a schema modificatio
Goal Determine whether a restored database backup can be considered in sync with the Liquibase changelog without generating false pending changesets due to backup‑time context or label settings. Constraints include the possibility that the backup was taken while a specific context or label was active, which may cause Liquibase’s validation and drift‑detectio
Nuxt 3 lets module authors declare configuration schemas via @nuxt/schema (using Zod or JSON Schema), and the app validates that configuration at boot. When validation fails, startup aborts with a validation error — there is no built-in mechanism to revert to a previously valid schema state. This makes any module schema change effectively a breaking change:
We expose an OpenAPI 3.1 specification that defines request constraints such as minLength , maxItems , pattern , and enum . On the server side, validation middleware generated from the same document rejects invalid payloads with 400 responses. On the client side, SDKs produced by Swagger Codegen appear to serialize and send values that violate those constrai
Element Cardinality Constraints and Parser Resource Bounds XML Schema (XSD) 1.0 and 1.1 permit the maxOccurs attribute to be set to unbounded , allowing an unrestricted number of element occurrences in a document instance. This flexibility creates a tension between schema expressiveness and parser resource consumption. When a DOM parser processes a document
