# Data Loader Behavior with Bulk API Enabled

Enabling the Bulk API in Data Loader lets you load or delete a large number of records faster than using the default SOAP-based API. However, there are some differences in behavior in Data Loader when you enable the Bulk API. One important difference is that it allows you to execute a hard delete if you have the permission and license.

|Required Editions|
|-----------------|
|Available in: both Salesforce Classic ([not available in all orgs](https://help.salesforce.com/s/articleView?id=xcloud.overview_edition_lex_only.htm&type=5)) and Lightning Experience|
|Available in: **Enterprise**, **Performance**, **Unlimited**, and **Developer** editions|

The following settings are not available on the **Settings** | **Settings** page in Data Loader when the `Use Bulk API` option is selected:

|Setting|Description|
|-------|-----------|
|Insert null values|This option enables Data Loader to insert blank mapped values as `null` values during data operations when the Bulk API is disabled. Empty field values are ignored when you update records using the Bulk API. To set a field value to `null` when the `Use Bulk API` option is selected, use a field value of `#N/A`.|
|Allow field truncation|This option directs Data Loader to truncate data for certain field types when the Bulk API is disabled. A load operation fails for the row if a value is specified that is too large for the field when the `Use Bulk API` option is selected.|
