What I encounter a lot is Redshift and Snowflake in the warehouse (more of the latter these days) supplemented by Databricks for Machine Learning (ML) and Spark support.
MLFlow to bring MLOps and model tracking into practice
but I still see most firms prefer a traditional Data Warehouse in their ecosystem as the center of data with Databricks as the big data compute and Machine Learning workhorse.

the Snowflake + Databricks partnership
the integration of installing UDFs into SnowFlake to embed custom routines in SQL seems a little clumsy compared to doing it in PySpark on Databricks — but I need to try it out a little before I can really be sure.
Snowpark like any new technology will take a few years to evolve to the point that it is as performant, stable, and robust as Spark on Databricks
