If you create a new schema `1-0-2` that reverts the offending changes and is again compatible with `1-0-0`, the data for events with that schema will be written to the original column as expected.

### Notes
:::note

- If events with incorrectly evolved schemas do not arrive, then the recovery column would not be created.
- It is still possible to break loading by overwriting version `1-0-0` of the schema. Please, avoid doing that.
If events with incorrectly evolved schemas never arrive, then the recovery column would not be created.

You can read more about schema evolution and how recovery columns work [here](/docs/storing-querying/schemas-in-warehouse/index.md?warehouse=bigquery#versioning).
