The following enhancements to the Data Loader improve usability, robustness and stability:
Data Loader interface
We removed some Advanced Options, and added instructional descriptions to the remaining options.
The template has been visually enhanced, and to avoid confusion, only editable (updateable) fields are now visible in the template.
Robustness and stability
The timeout for uploading bulk operations has been extended from 10 minutes to 15 minutes.
The size of a bulk request has been decreased from 20 items to 10 items.
The SOAP method has been replaced with a REST API, for improved robustness, flexibility, and logging capabilities.
