Azure Databricks features and specs

• Scalability
  Azure Databricks enables easy scaling of workloads up or down, allowing users to handle large volumes of data and perform distributed processing efficiently.
• Integration
  Seamlessly integrates with other Azure services, such as Azure Data Lake Storage and Azure SQL Data Warehouse, facilitating a streamlined data pipeline.
• Collaboration
  Offers collaborative features like notebooks that allow multiple users to work together easily on data analytics projects.
• Performance Optimization
  Built on top of Apache Spark, Azure Databricks provides high performance and optimized execution for data engineering and machine learning tasks.
• Managed Service
  As a fully managed service, it handles infrastructure provisioning and maintenance, enabling users to focus on data insights rather than backend management.

Possible disadvantages of Azure Databricks

• Cost
  Azure Databricks can be expensive, particularly for large-scale and long-running workloads, which may be a concern for budget-conscious organizations.
• Complexity
  Despite its capabilities, Azure Databricks may have a steep learning curve, especially for users not familiar with Apache Spark.
• Vendor Lock-in
  Leveraging Azure-specific services can lead to vendor lock-in, making it challenging to migrate workloads and data to other cloud platforms.
• Limited Offline Capabilities
  As a cloud-native service, it requires an active internet connection and might not suit scenarios that require offline processing.
• Compliance Concerns
  Due to Azure Databricks' integration with Azure, users need to carefully manage compliance and data governance, which might be complex in multi-regional deployments.
