Specifically this involves the following changes (not necessarily related, but combined in this PR) 1) When a connector provides its own column mapping info in the schema pre-populated we require that it's complete (i.e. fieldId AND physicalName must be present) 2) We add an argument to our schema validation checks `allowNewNonNullableFields`. This is useful in cases where we can be sure the table state has been completely cleared, and thus new non-null fields are valid (like REPLACE). 3) We don't allow adding a new column with a fieldId less than the maxColId. For now, do this proactively for safety. In the future in the case of something like RESTORE in the future we will likely need a config to bypass this check. ## How was this patch tested? Updates unit tests. Also, all the changes in this PR are used by delta-io#4520 which adds a lot more E2E tests with multiple schema scenarios. ## Does this PR introduce _any_ user-facing changes? No.
