Key Concepts of Databricks
By understanding the key concepts of Databricks, you can efficiently utilize it for your business operations. Here are some of its core aspects:
Workspace
Workspace is a cloud-based environment where your team can access Databricks assets. You can create one or multiple workspaces, depending on your organization’s requirements. It serves as a centralized hub for managing and collaborating Databricks resources.
Data Management
Databricks offer various logical objects that enable you to store and manage data, which you can use for ML and analytics. Let’s take a look at these components:
- Unity Catalog: Databricks Unity Catalog provides you with centralized access control, auditing, data lineage, and data discovery capabilities across Databricks workspace. All these features ensure that your data is secure, easily traceable, and accessible.
- Catalog Explorer: The Catalog Explorer allows you to discover and manage your Databricks data and AI assets. These assets include databases, tables, views, and functions. You can use Catalog Explorer to identify data relationships, manage permissions, and share data.
- Delta Table: All the tables you create within Databricks are Delta Tables. These tables are based on Delta Lake’s open-source project framework. It stores data in a directory of files on cloud object storage and stores metadata in metastore within the catalog.
- Metastore: This component of Databricks allows you to store all the structural information of the various tables in the data warehouse. Every Databricks deployment has a central Hive metastore, which is accessible by all the clusters for managing table metadata.
Computational Management
Databricks provides various tools and features for handling computing resources, job execution, and overall computational workflows. Here are some key aspects:
- Cluster: Clusters are computational resources that you can utilize to run notebooks, jobs, and other tasks. You can create, configure, and scale clusters using UI, CLI, or REST API. Multiple users within your organization can share a cluster for collaborative and interactive analysis.
- Databricks Runtime: These are a set of core components that run on Databricks clusters. Databricks Runtime includes Apache Spark, which substantially improves the usability, performance, and security of your data analytics operations.
- Workflow: The Workflow workspace UI of Databricks enables you to use Jobs and Delta Live Tables (DLT) pipelines to orchestrate and schedule workflows. Jobs are a non-interactive mechanism optimized for scheduling tasks within your workflows. DLT Pipelines are declarative frameworks that you can use to build reliable data processing pipelines.
Key Features of Databricks
Now that you’ve looked into the key concepts of Databricks, it would also help to understand some of its essential features for better utilization.
Databricks SQL
Databricks SQL is a significant component of the Databricks warehouse, enabling you to perform SQL-based queries and analysis on your datasets. With this feature, you can optimize the Lakehouse architecture of Databricks for data exploration, analysis, and visualization. By integrating it with BI tools like Tableau, Databricks SQL bridges the gap between data storage and actionable insights. This makes Databricks a robust tool for modern data warehousing.
AI and Machine Learning
Databricks offers a collaborative workspace where you can build, train, and deploy machine learning models using Mosaic AI. Built on the Databricks Data Intelligent Platform, Mosaic AI allows your organization to build production-quality compound AI models integrated with your enterprise data.
Another AI service offered by Databricks is Model Serving. You can utilize this service to deploy, govern, and query varied models. Model Serving supports:
- Custom ML models like scikit-learn or PyFunc
- Foundational models, like Llama 3, hosted on Databricks
- Foundational models hosted elsewhere, like ChatGPT or Claude 3
Data Engineering
At the core of Databricks’s data engineering capabilities are data pipelines. These pipelines allow you to ingest and transform data in real-time using Databricks structured streaming for low latency processing.
Another key feature is Delta Lake, the storage layer that provides ACID transactions, making it easier for you to manage large volumes of structured and unstructured data. Apart from this, Delta Live Tables allow you to automate pipeline management. It offers a simple and scalable solution to build and monitor production-grade pipelines with built-in quality checks.
These tools, combined with Databricks’ ability to scale computing resources, allow your team to build, test, and deploy data engineering solutions at speed.
Data Security
Databricks ensure robust data security through multiple layers of protection. It offers:
- Multilevel authentication and access control mechanisms, securing user access permissions within your workspace.
- IP access lists, which is a security feature that allows you to control access to your Databricks accounts and workspaces based on IP addresses. By configuring allow and block lists, you can specify which IP addresses or subnets are permitted or denied.
- Customer-managed Virtual Private Cloud that gives you control over network configuration. This helps you meet security and governance standards. It also enables isolation of Databricks workspaces from other cloud resources for a secure environment.
These techniques help safeguard your network, prevent data exfiltration, and ensure compliance with regulatory standards.
