Having pyspark and delta-spark as dependencies could cause problems in databricks. But for now this LGTM, we will modify if needed in the next coming pr's while we are re-architecting readers and writers.

pyspark = "^3.0.0"
delta-spark = "^2.1.0"
requests = "^2.28.1"

If it is a problem, we could also add the , optional = true flag to the delta-spark and requests package, and call out these as extra packages under [tool.poetry.extracts]`:

poetry install -E delta-spark -E requests

I also think we should have pyspark in the main package dependencies so it is a good and safe addition.

In the case where folk my not be using delta in the future it could be good to make that optional, I'm just thinking of this like supporting <scope>provided</scope> in typical maven project.
