Photon

Databricks' native vectorized query engine, written in C++, that accelerates Spark SQL and DataFrame workloads.

Definition

Photon is compatible with Spark APIs and is enabled on SQL warehouses and optionally on clusters. It speeds scans, joins, aggregations and Delta writes.

Exam tip

Photon accelerates SQL and DataFrame operations; it doesn't speed up Python UDF logic.
