CMS VRDC (Virtual Research Data Center) new platform is based on Databricks. I understand it has a database layer (called Delta). In order to run SQL, I think the flavor to use is Spark.
See links below (optional)
I have questions to the community:
Did you have to deal with Spark SQL flavor at your site (in relationship to OMOP CDM shaped data)?
Did you try to add Spark support to SqlRender (and with what results)? (how different is that flavor and can it be ever supported?)
