What is Databricks?

Data and data pipelines are the focus of businesses that drive their decisions through business intelligence. And to ensure the best use of data, businesses invest in different tools for data-related processes such as integration, processing, analysis, etc.

But managing this variety of data tools and maintaining efficiency becomes difficult, especially when companies want to scale up. The solution? A single tool that takes care of all data and business intelligence requirements.

Databricks is one such tool that offers complete, data warehouse solutions. It is a powerful data storage and analytics platform that can integrate with a number of BI tools and advanced analytical technologies such as AI.

Developed by the creators of Apache Spark, Databricks uses machine learning and distributed processing to speed up ETL processes - something that traditional data warehouses cannot do. This is useful for businesses that routinely process large volumes of data or continually rely on analytics.

‍An online electronics store, for instance, can use customer behavioural data to give personalized recommendations. If they use conventional data warehouses, processing will take hours or even days, delaying the recommendations.

‍On the other hand, Databricks processes data at short intervals delivering real-time recommendations. This means better personalization, customer experience, and more sales.

‍You can do much more by understanding how Databricks functions. In this article, we explain its features, architecture, and use cases. But first, let's understand what Databricks is.

What is DataBricks?

Databricks is a cloud-based platform that offers big data and machine learning services. It was founded by the creators of Apache Spark, a popular open-source big data processing framework, and provides a collaborative environment for data processing and machine learning. The platform integrates with cloud services such as AWS, Microsoft Azure, and Google Cloud, enabling organizations to leverage the advantages of the cloud, such as scalability, security, and lower costs.

‍Databricks provides an interactive notebook environment for data engineers and scientists to collaborate on data processing and machine learning tasks. It supports programming languages like Python, Scala, and SQL and integrates with big data technologies like Apache Hive, Apache Spark, and Apache Kafka. ‍

The platform also offers advanced analytics capabilities such as graph processing, time-series analysis, and streaming data processing.

‍Databricks provides a cost-effective solution for big data processing and machine learning compared to building and maintaining an in-house infrastructure. It offers a pay-per-use pricing model that enables organizations to only pay for the resources they use. The platform also provides enterprise-grade security features such as role-based access controls, data encryption, and secure data sharing, ensuring that sensitive data is protected and meets compliance requirements.

Features of Databricks

Databricks is a fast and reliable ETL tool that speeds up data processing by up to 10 times. It also has other features that make Databricks an excellent data processing platform for your business:

Interactive Notebooks

Databricks has an interactive notebook interface that can be used to write codes, comments, and explanations. The interface supports various programming languages like SQL, Python, and Scala. The notebooks help you easily manage project development by keeping track of code alterations and execution.


Databricks has a shared workspace with collaboration tools to manage notebooks among multiple users. You can share the notebooks among team members, enable suggestions, or even iterate them with Git to manage code changes. 

Collaboration tools such as comments and feedback are useful in taking recommendations from multiple users for solving complex code, implementing data processes, and so on.

Cloud Optimization

Databricks has a foundation of Apache Spark, which is highly suitable for a cloud interface. Through Apache Spark, Databricks can scale for any volume of data processing. 

For example, if there is a high demand for data processing at the start of the ETL process, the interface automatically scales clusters to quickly analyze all data. As the demand falls, the compute clusters also scale down to accommodate the fluctuating data levels.

The platform also manages pre-provisioned instances to reduce the time and capacity required for any data process in the cloud interface.

Data Analytics

With Databricks, you can connect to any cloud or on-premise data source to process large data volumes. It provides various analytics tools, including SQL processing, machine learning, integration, and visualization, to develop accurate insights. These tools can handle any number of queries in a short time to produce real-time results. 

Databricks Architecture

Databricks combines four open-source cloud tools in a data lake house architecture. Unlike data warehouses or data lakes, lake houses have advanced capabilities to run machine learning queries, simplifying ETL and business analytics. 

The platform can be connected with existing cloud storage platforms such as AWS or Google Cloud and placed on top of data warehouses. This data source supplies data to the other layers of the Databricks platform. 

Layers of Databricks Architecture

Databricks has an integrated user interface of four layers:

Data Lake

The data lake is the first storage layer that integrates all structured, unstructured, and semi-structured data. This can contain data from all pipelines, including CRMs, ERPs, social media platforms, emails, and company resources. The data in data lakes isn't organized and is stored in its native form.

Delta Lake

Delta Lake is an advanced storage layer that adds structure and reliability to the data lake. The layer adds a schema to the data lake to organize the data for analysis. It also ensures that all transactions in the data lake are atomic, consistent, isolated, and durable (ACID transactions). 

With Delta lake, you get features such as schema evolution, time traveling, and versioning that are unavailable in traditional data lakes. You can also use it for large volumes of data processing due to its Apache Spark build.

Delta Engine

Delta engine is a query processing engine that runs large-scale queries on data stored in Delta lake. The engine uses a distributed framework to automatically optimize query processing depending on the queries' volume, size, and complexity. 

This improves Delta lake workload efficiencies and allows for large-scale batch data processing. Delta engine also provides automatic indexing and caching to improve Delta lake performances.

Other Tools

After query processing, the data can be used for various analytics and business intelligence processes. Databricks provides built-in tools for almost every BI use case, including machine learning, visualization, and notebooks. Moreover, it is also integrable with other analytics tools such as Redash, MLFlow, and Power BI.

The four-layer architecture of Databricks is optimal for complex or large-scale data processing and machine learning requirements. You can further utilize Databricks for your business by learning about the importance of the platform.

What format does Delta Lake use to store data?

Delta Lake uses versioned Parquet files to store your data in your cloud storage. Apart from the versions, Delta Lake also stores a transaction log to keep track of all the commits made to the table or blob store directory to provide ACID transactions.

Where does Delta Lake store the data?

When writing data, you can specify the location in your cloud storage. Delta Lake stores the data in that cloud account location in Parquet format.

Can I copy my Delta Lake table to another location?

Yes you can copy your Delta Lake table to another location. Remember to copy files without changing the timestamps to ensure that the time travel with timestamps will be consistent.

Can I stream data directly into and from Delta tables?

Yes, you can use Structured Streaming to directly write data into Delta tables and read from Delta tables. See Stream data into Delta tables and Stream data from Delta tables.
