Databricks Basics


                   Databricks Basics

  • Here’s a breakdown of Databricks basics to get you started!

    What is Databricks?

    • Unified Analytics Platform: Databricks is a cloud-based platform that integrates data engineering, data science, and machine learning. It’s built on Apache Spark, providing enhanced performance and ease of use.
    • The Lakehouse Concept:  Databricks champions the “Lakehouse” architecture. This combines the flexibility of a data lake (the ability to store all your data, structured and unstructured) with the reliability and management features often found in data warehouses.

    Key Components

    1. Workspaces:  The collaborative environment where you work in Databricks. Workspaces contain:
      • Notebooks: Interactive documents allowing you to write code (Python, SQL, Scala, R), create visualizations, and document your work.
      • Clusters:  The compute resources (think virtual machines) that power your data processing and analysis within Databricks.
      • Jobs: Scheduled tasks used to automate data pipelines and workflows.
      • Data: Databricks integrates with your cloud storage (like Azure Blob Storage, AWS S3) to access and process data.
    2. Databricks File System (DBFS): A distributed file system layer optimized for Spark, making it easy to work with data stored in your cloud storage.
    3. Delta Lake:  An open-source format that builds upon Parquet files to bring features like:
      • ACID Transactions: Maintains data consistency and integrity
      • Reliability: Ensures data quality even when errors occur during a job.
      • Time Travel: Access historical versions of your data.

    Why Use Databricks?

    • Simplified Big Data Processing: Handles the complexities of setting up and managing Spark clusters.
    • Unified Environment: Supports the entire data workflow from ETL to machine learning in a single platform.
    • Collaboration:  Workspaces promote easy teamwork.
    • Performance:  Optimized Spark engine for speed and efficiency.
    • Cloud Integration: Seamless integration with Azure, AWS, and GCP services.
