What am I passing as the bucket url to SDKs? Just the

<lakefs://quickstart/main/>

url? Or something else?

Yes, if you use lakeFSFS. If you use S3A Gateway then

<s3a://quickstart/main/>

ahah, what I'd been looking for!

Here are few Databricks Spark samples but it applies to Apache Spark also: https://github.com/treeverse/lakeFS-samples/tree/main/01_standalone_examples/aws-databricks

righto - I'm using an Elixir lib right now to handle it 🙂
