Databricks is an integrated data analytics tool that was developed by the same team that created Apache Spark. The platform meets the requirements of Data Scientists, Data Analysts, and Data Engineers in deploying Machine Learning techniques to derive deeper insights into big data in order to improve productivity and bottom line. Databricks was developed by the same team that created Apache Spark. It had been successful in overcoming the difficulty of the local warehouses to manage unstructured formats of a large volume of data that was generated from everywhere. In this article, let us look at Azure Databricks Interview Questions Answers to understand this tool fully. 

1. In a nutshell, what does “Databricks” mean?

A big data platform that is hosted in the cloud may be used to manage data lakes, process the data using machine learning methods, and get valuable insights from the data.

2. Who are the users that stand to benefit the most from Databricks?

Data Scientists, Data Analysts, and Data Engineers may get the most valuable insights possible from huge data with the help of Databricks

3. What are the different parts that make up Databricks?

  • a venue for programmers to work together on code in real-time while maintaining their privacy.
  • Managed Clusters to accelerate the processing speed of queries.
  • Spark Engine is used to handle the processing of data in memory.
  • In order to make up for the deficiencies of traditional data lake file formats, Delta was developed.
  • ML Flow as a means of overcoming difficulties in manufacturing a growing ML lifecycle
  • SQL Analytics is used to create queries for the purpose of extracting data from data lakes and publishing it in dashboards.

4. What programming languages does Databricks offer support for?

R, Python, Scala, Standard SQL, and Java are the languages that are used. Additionally, it is compatible with a number of different application programming interfaces (APIs), including SparkR, SparkylR, PySpark, Spark SQL, and Spark.api.java.

5. What sets data lakes and data warehouses apart from one another?

The majority of the data in the data warehouse has been processed and is structured. This data is necessary for business analysis, and the data warehouse is handled in-house using local capabilities. It is not possible to make significant alterations to its structure. Data lakes store all data, including raw data and old data. They are also capable of storing all forms of data, including unstructured data; they are simple to scale up, and the data model may be altered quickly. It is maintained by tools hosted by a third party, preferably in the cloud, and it makes use of parallel processing when it is processing the data.

6. Does Databricks solely have a cloud-based deployment option, and does it not have a local installation option?

Yes. Apache Spark, which is the foundational version of Databricks, was made available as an on-premises solution, and in-house engineers were able to manage the application and keep the data up to date locally. Since Databricks is a cloud-native service, users that access the application using data stored on local servers will experience difficulties with the network. On-premises options for Databricks are evaluated negatively for a number of reasons, including the potential for inconsistent data and inefficient workflows.

8. Is Microsoft the company that actually owns Databricks?

No. Even today, Databricks is an open-source product that was developed on Apache Spark. In 2019, Microsoft has made an investment of two hundred and fifty million dollars. Azure Databricks was initially published in 2017 after Microsoft included a number of Databricks’ services into its cloud computing platform Azure. A similar network of partnerships is in existence with Google Cloud Platform (GCP) and Amazon Web Services (AWS).

9. What sets Azure Databricks apart from traditional Databricks?

Databricks united Apache Spark’s processing capability of data analysis and ML-driven data science/Engineering methodologies in order to manage the full data lifecycle, beginning with the state of ingesting data and progressing all the way to the stage of consuming it.

Azure Databricks integrates some of Azure’s capabilities with the analytics tools of Databricks to provide the end user with the most advantageous aspects of both platforms in a single convenient package. It combines the AI-driven analytics power of Databricks with Azure’s own data extraction tool, Data Factory, for Transformation and Loading, and it employs Azure’s own data extraction tool, Data Factory, for pulling data from a variety of sources. In addition to this, it employs the integration features of Microsoft Active Directory to get authentication, as well as other Azure and general functions of Microsoft, in order to boost productivity.

10. What kind of cloud services does Databricks offer, and how do they categorize themselves? Is it a SaaS, PaaS, or IaaS model?

The goal of the Software as a service (SaaS) that is provided by Databricks is to take advantage of the capability that clusters of Spark nodes can bring to the table when it comes to managing storage. Users will just need to make changes to the application configurations before they can begin deploying the applications.

11. Which category of cloud services does Azure Databricks fall under? Is it a SaaS, PaaS, or IaaS model?

PaaS is an abbreviation that stands for “platform as a service,” which describes the type of service that Azure Databricks provides. It offers a platform for application development with capabilities constructed using Azure and Databricks. Users will be required to create and develop the data life cycle in addition to developing apps by utilizing the services that are provided by Azure Databricks.

12. Contrast the Azure Databricks with AWS Databricks platforms.

Azure Databricks is a product that offers both Azure and Databricks functionalities, yet they are integrated together quite nicely.

It’s not just a simple hosting service for Databricks on Microsoft’s Azure platform. Azure Databricks is a superior offering thanks to Microsoft features such as Active directory authentication and integration with a large number of Azure functions. The AWS Databricks service is essentially just hosting for Databricks on the AWS cloud.

Conclusion

With the proliferation of smartphones and the increasing availability of high-bandwidth internet, a new generation of applications is being built, and by default, these applications are hosted in the cloud. The use of Databricks will facilitate and speed up the development of such technologies to a higher degree. In this article focusing on Azure Databricks Interview Questions Answers, we hope you have been able to fully comprehend the gist of the tool.
