Key Concepts of Azure Databricks

Workspace: The Azure Databricks workspace is an interactive environment where users can create, manage, and organize their data solutions. It includes notebooks, libraries, and dashboards.

Clusters: Clusters in Azure Databricks are collections of virtual machines that perform computations.

Notebooks: Notebooks are interactive documents that combine code, visualizations, and narrative text.

Jobs: Jobs are automated processes that run notebooks or scripts on a schedule. They help in managing and orchestrating complex workflows.

Delta Lake: It ensures data reliability and improves query performance by enabling scalable and fast data lake operations.  Data Engineer Course in Hyderabad

Implementing Parallelism in Notebook Execution

Parallel Processing with Spark:

Azure Databricks Utilize Apache Spark's parallel processing capabilities to distribute tasks across multiple nodes in a cluster in.

·     Use Spark transformations like map, filter, and reduce to process data in parallel.

Parallel Notebook Execution:

·        Divide the notebook into smaller, independent tasks that can be executed concurrently.

·        Leverage dbutils.notebook.run command to call multiple notebooks in parallel.

Auto-scaling Clusters:

Configure clusters to auto-scale, allowing resources to be dynamically allocated based on workload.

Ensure that the cluster size and configuration match the parallelism requirements to avoid resource contention.  Data Engineer Training Hyderabad
