[SalesForce] How to set the concurrencyMode using the new Bulk API 2.0

Bulk API 2.0 simplifies uploading large amounts of data by breaking the files into batches automatically. All you have to do is upload a CSV file with your record data and check back when the results are ready.

Files must be in UTF-8 format. Files are converted to base64 when received by Salesforce. This conversion can increase the data size by approximately 50%. To account for the base64 conversion increase, upload data that does not exceed 100 MB.

I saw a Bulk API 2.0 presentation at TrailheaDX where this came up... I think it's a no, Bulk 2.0 is designed to ingest one data file and then start processing. Recall though that the limits on Bulk 2.0 are by volume of records not number of batches.

If you weren't expecting more batches of CSV data to be uploaded why not mark the job as complete automatically and dispense with this API call.

One possible reason is, networks can be unreliable. A disruption in the transfer could create a state where, for example, the client believes the transfer was incomplete because it didn't receive an acknowledgement packet, but in fact the server did receive the file. If it got marked as complete automatically, it would start processing even though the client thought it had failed.
