Unable to read s3 table: Unknown scheme: s3

Environment

Bug

What happened: The specified table_uri is not valid: InvalidTableLocation("Unknown scheme: s3") when trying to read a table with open_table_with_storage_options.

What you expected to happen: The table to be opened.

How to reproduce it: Try to read a table from s3 with open_table_with_storage_options. Something like this:

async fn read_table() -> Result<DeltaTable> {
    deltalake::open_table_with_storage_options(
        path,
        storage_options
    ).await?
}

More details: Yes, I am using the "s3" feature

This is not a "bug" so much as a "feature" 😄

main has unreleased changes which fully remove the AWS support code into the deltalake-aws crate. In order to make that possible, the user must now let the core code what available storage handlers exist. Here's an example of this being done in the Python code here

Gotcha, thanks! I'll give this a shot!

Looks like adding deltalake::aws::register_handlers(None) does the trick
