[SalesForce] Find objects that are supported through Bulk API

I don't believe this options exists for the bulk API. Based on General Guidelines for Data Loads in the Bulk API documentation I conclude it always executes in way similar to having AllOrNone=false.

The Bulk API doesn't generate an error immediately when encountering a lock. It waits a few seconds for its release and, if it doesn't happen, the record is marked as failed. If there are problems acquiring locks for more than 100 records in a batch, the Bulk API places the remainder of the batch back in the queue for later processing. When the Bulk API processes the batch again later, records marked as failed are not retried. To process these records, you must submit them again in a separate batch. If the Bulk API continues to encounter problems processing a batch, it's placed back in the queue and reprocessed up to 10 times before the batch is permanently marked as failed. Even if the batch failed, some records could have completed successfully. To get batch results to see which records, if any, were processed, see Getting Batch Results. If errors persist, create a separate job to process the data in serial mode, which ensures that only one batch is processed at a time.

Over Twitter I was able to get an answer to question. In short, Bulk API really isn't the right framework to help with sort of problem. The Bulk API is most helpful for mass inserting/updating/deleting. It isn't really that much more efficient when querying. It would be great if the Bulk API could break a query with many results into chunks of 2000 rows. That way, the job could download all of those chunks in parallel. In theory, it's possible to do this, but you as the developer will need to determine all of the chunks (queries) and then add them all to the job. It would be amazing if the Bulk API could 'chunkify' the query for you. As of today, it cannot.

So, I found it simpler to just use the normal queryAll() calls through the WebAPI and do 10 queries at a time (using Spring Batch). The only downside is that you can only have 10 query locators open at a time.

So, I don't have a solution of how to do this with the bulk API. In fact, if you want archived Tasks it's not possible because it does NOT support the ALL ROWS keywords.
