wjones127 opened a new issue, #2185:
URL: https://github.com/apache/arrow-datafusion/issues/2185

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   We are looking at improving the filesystem / object store support in 
delta-rs, but it seems like it would be better to work on that inside of 
datafusion's data-access crate instead of doing all that work in delta-rs. 
delta-rs currently has file system support for local fs, gcs, s3, and adls, 
with just reading and write whole files. I think we'll want to add streaming 
reads and writes.
   
   **Describe the solution you'd like**
   
   Design and implement a streaming write interface into the `ObjectStore` 
trait.
   
   
   **Describe alternatives you've considered**
   
   We could do that work in delta-rs and then contribute it back here later. 
But it might not transfer well. For example, the current delta-rs S3 filesystem 
use rusoto, while the datafusion object store uses the AWS SDK.
