Is it possible to reduce the size of the retrieved files in the Salesforce Bulk API. Currently it creates multiple files with a maximum size of 1Gb. I would like to reduce that limit to ~100Mb. The obvious solution is to do multiple queries but it would be a lot simpler if the batches could be limited.
Current infrastructure of Bulk API does not allows user to split result from one query. So the only option is to fire multiple queries.
