Databricks vs. Apache Spark: Understanding the Differences
Apache Spark is an open-source data processing engine known for its speed, ease of use, and versatility in handling various data processing tasks such as data integration, interactive analytics, machine learning, and real-time data processing.
Databricks, on the other hand, is a managed Spark service founded by the creators of Apache Spark. It simplifies the deployment and management of Spark by offering features like interactive notebooks, simplified cluster management, native cloud integration, and built-in tools such as MLflow and Delta Lake.
Key Differences
- Setup and Management: Databricks requires minimal setup and offers automated cluster management, while Apache Spark requires manual configuration and management.
- Scalability: Databricks provides automatic scaling, whereas Apache Spark requires manual scaling efforts.
- Performance Optimization: Databricks includes built-in optimizations like Photon, while Apache Spark requires manual tuning.
- Cost: Databricks operates on a pay-as-you-go model, which can be more expensive than managing your own Spark infrastructure.
