-
Spark 2 currently only supports access via the Dataframe API due to weak generic catalog support. ↩
-
Spark 3 supports both SQL and dataframe access. Consumption can be done via existing Iceberg and Delta Lake catalogs with Nessie extensions or through the Nessie Catalog, which currently exposes both of these formats. ↩
