The databricks deltas are hard for snowflake to read?

what cloud is hosting your databricks environment?

on azure what we did was create a sql server with a polybase connection to read out of the same blob that databricks was writing to. We then can connect snowflake or really any other source to the polybase enable sql server.

We have had success with federated connections into databricks as well. However, I think your best bet is accessing the delta/parquet etc at the blob level with a tool that interfaces well with snowflake
