Thanks for the PR! I tested this PR on a Databricks cluster and encountered a DeltaProtocolError. It appears the deltalake reader used here isn't compatible with tables that use Deletion Vectors or Column Mapping (which are now enabled by default on Databricks). Relevant discussions: delta-io/delta-rs#1094

  • Databricks runtime: 15.4 LTS

  • deltalake version: 1.2.1

  • Error Trace:

DeltaProtocolError: The table has set these reader features: {'deletionVectors'} but these are not yet supported by the deltalake reader.
