Databricks runtimes are the set of core components that run on Databricks clusters. Databricks offers several types of runtimes.
- Databricks Runtime
Databricks Runtime includes Apache Spark but also adds a number of components and updates that substantially improve the usability, performance, and security of big data analytics.
- Databricks Runtime ML
Databricks Runtime ML is a variant of Databricks Runtime that adds multiple popular machine learning libraries, including TensorFlow, Keras, PyTorch, and XGBoost.
- Photon runtime
Photon is the Databricks native vectorized query engine that runs SQL workloads faster and reduces your total cost per workload.
- Databricks Light
Databricks Light provides a runtime option for jobs that don’t need the advanced performance, reliability, or autoscaling benefits provided by Databricks Runtime.
You can choose from among the supported runtime versions when you create a cluster.
For information about the contents of each runtime variant, see the release notes.
