Databricks is a web-based platform and enterprise software developed by the creators of Apache Spark. It is a unified Cloud-based Data Engineering platform focusing on Big Data collaboration and Data Analytics by letting users combine Data Warehouses, Data Lakes, and data from other sources in one place to create a Lakehouse.

Databricks offers a versatile workspace for Data Engineers, Data Scientists, Business Analysts, and Data Analysts to collaborate using Collaborative Notebooks, Machine Learning Runtime, and managed ML Flow. Databricks was founded as an alternative to MapReduce to process Big Data.

Databricks is built on top of Apache Spark, a fast and generic engine for Large-Scale Data Processing. It delivers reliable and high performance. Databricks also supports integration with leading Cloud service providers – Amazon Web Services, Microsoft Azure, and Google Cloud Platform. It comes with Delta Lakes which is an Open Format Storage Layer that assists in handling scalable Metadata, unifying streams, and batch data processing.

Key Features of Databricks 

A few key features of Databricks are listed below:

  • Data Compression: Databricks supports data streaming, SQL queries, and Machine Learning. It takes up a huge volume of data, so Databricks comes with a unified Spark Engine to compress data at large scales.
  • Collaborative Notebooks: Databricks supports many languages and tools that allow you to access data, analyze it, discover new insights and, build new models using their interactive notebooks. The language supported is Python, Scala, R, and SQL.
  • Integrations: Databricks supports integrations with many tools and IDEs like PyCharm, IntelliJ, Visual Studio Code, etc. to make the Data Pipelining more organized. You can also integrate Datbricks with other cloud data storage platforms such as Azure Data Lake Storage, Google BigQuery Cloud Storage, Snowflake, etc., to fetch data in the form of CSV, XML, JSON format.
  • Machine Learning Features: Databricks offers many pre-configured Machine Learning environments leveraged with powerful frameworks such as PyTorch, TensorFlow, and Scikit-learn. You can track share experiments, reproduce runs, and manage models collaboratively.

What is REST API?

REST API stands for Representational State Transfer Application Programming Interface is a data source’s frontend that allows users to create, retrieve, update, and delete data items.

It is a software architecture style that is used for guiding the development of the architecture. Dr. Roy Fielding described REST API in 2000 giving developers flexibility and an approach to link components and applications in a microservices architecture because of their versatility.

REST API defines how 2 applications communicate with each other over HTTP. An HTTP request access and use the data with PUT, GET, POST and DELETE command. The components are loosely coupled which makes the data flow through HTTP fast and efficient. 

Key Features of REST API

A few features of REST API are listed below:

  • Flexible: REST APIs are flexible as they allow users to make multiple types of calls in different formats. It makes it if possible for users to communicate efficiently with client servers even they are hosted on different servers.
  • Layered: REST APIs keep the client, and the server decoupled that makes calls and responses of the REST APIs go through different layers. The layered system makes the APIs scalable.
  • Stateless: The server keeps no information about the user who uses the API. The requests sent from a client to a server will include all of the necessary information for the server to comprehend the client’s requests.
Methods to Connect to Databricks APIs

Method 1: Invoking Databrick API Using Python

In this method, you will use Databricks REST APIs and manually code in Python to connect Databricks API to any other app or service. You will manually send POST and GET requests using Python to Databricks.

Method 2: Invoking Databrick API Using cURL

This method will use cURL to connect to Databricks APIs and you will learn how to send and receive messages and responses from Databricks using its API. This process is manual and time-consuming for making bulk data requests.

Method 3: Connect Databricks APIs Using Hevo Data

A fully managed, No-code Data Pipeline platform like Hevo Data, helps you load data from 100+ Data Sources (including 40+ free sources) to Databricks in real-time, in an effortless manner. Hevo, with its minimal learning curve, can be set up in a matter of minutes, making the users ready to load data without compromising performance.

Its strong integration with various sources such as databases, files, analytics engines, etc. gives users the flexibility to bring in data of all different kinds in a way that’s as smooth as possible, without having to write a single line of code.

What are the Methods to Connect to Databricks APIs?

Now that you have understood Databricks and REST API and why Databricks API is important for developers to connect to other apps and platforms. In this section, you will learn how to connect to Databricks API to request data. The 3 methods to access Databricks API are listed below:

Method 1: Invoking Databrick API Using Python

In this method, python and the request library will be used to connect to Databricks API. The steps are listed below:

Step 1: Authentication Using Databricks Access Token

  • Log in to your Databricks account.
  • Click on the “Settings” button located in the lower-left corner of the screen.
  • Then, click on the “User Settings” option.
  • Now, switch to the “Access Token” tab.
  • Here, click on the “Generate New Token” button to generate a new personal access token for Databricks API.
  • Now, click on the “Generate” button.

  • Copy the access token that you just generated and store it in a safe location.

Step 2: Storing the Token in .netrc File

  • Now create a file with .netrc and add machine, log in, and password properties in the file. The syntax for the file is shown below.
machine <databricks-instance>
login token
password <token-value>
  • Here, the <data-instance> is the Instance ID part of your Workspace URL for Databricks Deployment.
  • Let’s say your Workspace URL is then the instance ID or <databricks-instance> is
  • The token is the literal string token.
  • The <token-value> is the value of the token you copied. For example: api1234567890ab1cde2f3ab456c7d89efa.
  • Finally, after creating the .netrc file, the resulting file will look similarly as shown below:
login token
password dapi1234567890ab1cde2f3ab456c7d89efa

Step 3: Accessing Databricks API Using Python

  • Open any code editor that supports Python.
  • For invoking Databricks API using Python, the popular library requests will be used for making HTTP requests. You will go through the process of getting the list of information about specific Databricks clusters. 
  • Here, the .netrc file will be used to pass the credentials.
  • The code for accessing Databricks API using Python is given below:
import requests
import json

instance_id = ''

api_version = '/api/2.0'
api_command = '/clusters/get'
url = f"https://{instance_id}{api_version}{api_command}"

params = {
  'cluster_id': '1234-567890-batch123'

response = requests.get(
  url = url,
  params = params

print(json.dumps(json.loads(response.text), indent = 2))
  • Here, first, you need to import 2 libraries then provide all the information regarding instance ID, app commands, app versions, URL to call, additional parameters for the cluster, etc. 
  • After running the code, the finalized result will look like as shown in the image below:
  "cluster_id": "1234-567890-batch123",
  "spark_context_id": 1234567890123456789,

Method 2: Invoking Databrick API Using cURL

In this method, cURL is used to access Databrick APIs. It follows simple cURL command in the terminal window. The steps are listed below:

  • Follow Step 1 and Step 2 of Method 1, if you haven’t created the .netrc file yet. Else skip it.
  • Open your terminal window and write the commands as given below.
curl --netrc --get 
--data cluster_id=1234-567890-patch123
  • Here, replace the with your Workspace URL. 
  • After completing the command correctly with your credentials, URL, and cluster-ID. The result will look similarly as given below.
  "cluster_id": "1234-567890-patch123",
  "spark_context_id": 123456789012345678,
  "cluster_name": "job-239-run-1",
  "spark_version": "8.1.x-scala2.12",
