:validate_uniqueness | `true`/`false` | `false` | Whether or not to run uniqueness validations, has potential pitfalls, use with caution (requires `>= v0.27.0`).
:validate_uniqueness | `true`/`false` | `false` | Whether or not to run ActiveRecord uniqueness validations. Beware this will incur an sql query per-record (N+1 queries). (requires `>= v0.27.0`).

:track_validation_failures| `true`/`false` | `false` | When this is set to true, `failed_instances` will be an array of arrays, with each inner array having the form `[:index_in_dataset, :object_with_errors]`
:on_duplicate_key_ignore | `true`/`false` | `false` | Allows skipping records with duplicate keys. See [here](#duplicate-key-ignore) for more details.
