Databricks System Design Style
Databricks system design style refers to the Lakehouse architecture — a unified data platform that blends the scalability of data lakes with the reliability and performance of data warehouses, enabling collaborative analytics, ML, and streaming at scale.
When to Use
Use this approach when teams need to process massive datasets, perform machine learning, or build real-time analytics pipelines across cloud environments without data silos.
Example
A retail company might use Databricks to unify raw customer data from multiple sources, clean it using Spark, and train ML models for personalized recommendations — all in one platform.

Why Is It Important
Databricks simplifies modern data workflows by offering scalable compute, Delta Lake for ACID transactions, and seamless collaboration for data engineers, analysts, and ML teams.
Interview Tips
Focus on concepts like Delta Lake, metadata management, and decoupled compute-storage design. Explain how Databricks handles both batch and streaming data efficiently using Apache Spark.
Trade-offs
Databricks offers unified power and scalability but comes with trade-offs like cloud dependency, higher costs, and steep learning curves for distributed compute.
Pitfalls
Avoid thinking of Databricks as just a database; it’s a distributed data platform. Mismanaging cluster configurations or not optimizing Spark jobs can lead to costly inefficiencies.
