# Change Log

Every data table includes a built-in changelog that records modifications. It provides an audit trail that shows who made each change, when the change occurred, and what it affected.

## Opening the changelog

You can open the changelog in two ways:

- Go to **Settings** > **Data Tables**, and then click the **History** icon next to a table.

- Open a table’s details page, and then click **History** in the upper-right corner.

The **Change Log** dialog lists entries in pages. The most recent changes appear first.

## What the changelog tracks

The changelog records the following information for each entry:

| Field             | Description                                                                        |
| ----------------- | ---------------------------------------------------------------------------------- |
| **Date**          | When the change occurred                                                           |
| **Operation**     | The type of change (refer to the [operation types](#operation-types)) section below |
| **Summary**       | A one-line description of the change (diff for updates, row count for imports)     |
| **Row/Column ID** | The primary key value of the affected row, or the column name for schema changes   |
| **User**          | Who made the change                                                                |

### Operation types

| Operation               | Description                                                    |

| **Update**              | A row was modified                                             |
| **Delete**              | A row was removed                                              |
| **Import**              | Rows were added via CSV import                                 |
| **Add Column**          | A column was added to the table schema                         |
| **Drop Column**         | A column was removed from the table schema                     |
| **Rename Column**       | A column was renamed                                           |
| **Alter Column**        | A column’s data type or properties were changed                |
| **Create Table**        | The table was created through the create table wizard          |
| **Rename Table**        | The underlying table was renamed                               |

| **Unregister Table**    | A table registration was removed                               |

The UI color-codes operation types:

- **Green** — Insert operations and Register Table

- **Blue** — Update operations

- **Red** — Delete operations and Unregister Table

- **Teal** — Import operations

- **Purple** — Schema operations (add/drop/rename/alter columns, create/drop/rename table)

- **Orange** — Update Registration (display name, description, or repointing to a different connection/table)

## Viewing change details

To view the full details of a change, click the arrow at the start of a changelog entry. The entry expands inline and shows old and new values in a **Field**, **Old Value**, and **New Value** table.

- For **insert** operations, old values are empty and new values show the inserted data.

- For **update** operations, both old and new values are displayed so you can view exactly what changed.

- For **delete** operations, old values show the data that was removed, and new values are empty.

- For **import** operations, a single changelog entry summarizes the entire import. Expanding the entry shows the imported rows in a subgrid.

## Bulk import logging

Each CSV import creates one **Import** entry in the changelog. The summary shows the total number of inserted and failed rows. Expand the entry to review all imported rows.

## Permissions

Users need the **View** (`viewconfig`) permission on the table to view the changelog. Any user who can view the table data can also view its changelog.

## Limitations

- The changelog is append-only. Entries can’t be edited or deleted.

- The platform doesn’t include a built-in rollback function. To undo a change, manually reverse it. For example, reinsert a deleted row or restore an updated value.

- Changelog entries have a configurable retention period. Entries older than the retention period are automatically purged.
