# Amazon S3

You can use the Amazon S3 connector from the CData Sync application to capture data
from Amazon S3 and move it to any supported destination. To do so, you need to add
the connector, authenticate to the connector, and complete your connection.

## Supported File Formats

When Sync writes data to Amazon S3, you can choose the file format for the exported data. The following file formats are supported for the Amazon S3 source:

* (Default) **CSV:** Plain text comma-separated values.
* **Avro:** A row-based binary format that supports schema evolution.
* **Parquet:** A columnar storage format that is optimized for analytics.

## Add the Amazon S3 Connector

To enable Sync to use data from Amazon S3, you first must add the
connector, as follows:

<ol>
  <li>Open the **Connections** page of the Sync dashboard.</li>
  <li>Click **Add Connection** to open the **Select Connectors** page.</li>
  <li>Click the **Sources** tab and locate
  the **Amazon S3** row.</li>

  <li>
    Click the **Configure Connection** icon at the end of that row to open
    the **New Connection** page. This action opens the
    **Add Connection** dialog.

    **Note:** If the **Configure Connection** icon is not
    available, click the **Download Connector** icon to install
    the Amazon S3 connector.
  </li>

  <li>Enter a name for your connection in the **Add Connection** dialog.</li>
  <li>Click **Add** to open the **Settings** tab for your connector.</li>
</ol>

For more information about installing new connectors, see
[Connections](https://docs.sync.cdata.com/26.4/en/connections/connections.md).

## Authenticate to Amazon S3

After you add the connector, you need to set the required properties.

* **File Format:** Select the file format that you want to use: **Delta Parquet**, **CSV** (default), **Avro**, and **Parquet**.

  > [!NOTE]
  >
  > The **Delta Parquet** and **Apache Iceberg** file formats are not supported for Sync source connectors. If you select either of these formats, Sync generates an error.

* **URI:** Enter the path of your bucket and folder (for example, `s3://BucketName/FolderName`).

CData Sync supports authenticating to Amazon S3 in several ways. Select your authentication method below to proceed to the relevant section that contains the authentication details.
