### Sync overview <a href="#syncoverview" id="syncoverview"></a>

#### Rollback sync <a href="#rollbacksync" id="rollbacksync"></a>

A rollback sync is a sync that automatically starts once a day. Rollback syncs capture the conversions within the attribution window.

Fivetran does not automatically capture the rollback window size. You can opt to configure the rollback window in the connection setup form. To do so, set the **Show advanced options** toggle to ON, and set the attribution window using the **Rollback sync (optional)** drop-down. The default setting is 7 days.

### Schema information <a href="#schemainformation" id="schemainformation"></a>

### Report schema information <a href="#reportschemainformation" id="reportschemainformation"></a>

We provide two types of reports:

* Prebuilt reports, which sync a pre-defined set of metrics. For prebuilt reports, we have predefined tables in the **Schema** tab that you can enable or disable.
* Custom reports, which require you to select the Report Level, Dimensions, Aggregate, and Metrics you want to sync in the connection setup form.

### Sync notes <a href="#syncnotes" id="syncnotes"></a>

The data type of the following columns in the destination tables is LONG:

* `ad_id`
* `adgroup_id`
* `advertiser_id`
* `app_id`
* `campaign_id`
* `event_id`
* `pangle_block_app_list_id`
* `pixel_id`

The data type of the `skip_learning_phase` column of the `ADGROUP_HISTORY` table is INT.

Due to source API limitation, we can fetch only the first `10000` videos per advertiser ordered by `updated_at` (also referred to as `modify_time` in the source documentation) for the `VIDEO_HISTORY` table in every sync.
