Yes, 

First of all, open source spark already has a set of auto-tuning features denominated Adaptive Query Execution (AQE). Here are more details: https://spark.apache.org/docs/latest/sql-performance-tuning.html#adaptive-query-execution.

For even better auto-tuning capabilities, Databricks offer it's Photon Engine that is a highly optimized engine for spark that explores spark's AQE features much further than the OSS spark engine. 

Databricks SQL is also a highly optimized product that doesn't need manual tuning of your workloads. DBSQL relies on Photon.
