Hello, The Iceberg Terraform provider <http://github.com/apache/iceberg-terraform>uncovered the fact that the REST Fixture does not validate any id values (schema-id, field-id, last-partition-id, etc) for duplication. This is one of many validations the Fixture can perform.
I've raised a PR <https://github.com/apache/iceberg/pull/16148> to fix this, but it's kicked off a conversation about the level of validation that the REST Fixture should have. I propose that the REST Fixture should validate the inputs as much as possible, especially since all of our implementations test against the fixture. Adding validations to the fixture will ensure that we can catch downstream errors in the implementations. Please take a look at the PR and I'd appreciate any community opinions regarding the desired functionality level for the REST Fixture. Thanks, Alex Stephen
