Tishj opened a new issue, #13305: URL: https://github.com/apache/iceberg/issues/13305
### Apache Iceberg version 1.9.1 (latest release) ### Query engine None ### Please describe the bug 🐞 There is a `discriminator`, but no accompanying `oneOf` or `anyOf` directive. ```yml TableRequirement: type: object discriminator: propertyName: type mapping: assert-create: '#/components/schemas/AssertCreate' assert-table-uuid: '#/components/schemas/AssertTableUUID' assert-ref-snapshot-id: '#/components/schemas/AssertRefSnapshotId' assert-last-assigned-field-id: '#/components/schemas/AssertLastAssignedFieldId' assert-current-schema-id: '#/components/schemas/AssertCurrentSchemaId' assert-last-assigned-partition-id: '#/components/schemas/AssertLastAssignedPartitionId' assert-default-spec-id: '#/components/schemas/AssertDefaultSpecId' assert-default-sort-order-id: '#/components/schemas/AssertDefaultSortOrderId' properties: type: type: string required: - type ``` To me this looks like it violates this rule defined in the [spec](https://swagger.io/specification/) under "Discriminator Object": > Note that discriminator MUST NOT change the validation outcome of the schema. As such, this object has a single field `type`, because there is no directive to change the shape of the schema, `discriminator` can't change the schema, it can only provide a hint for more efficient discovery of the matching variant (referencing an item of the `oneOf`, `anyOf`) ### Willingness to contribute - [ ] I can contribute a fix for this bug independently - [ ] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [x] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
