So, What is Databricks, and What do People Use it for?

Databricks Processes Data

Databricks is a versatile platform that handles ETL/ELT tasks, such as reading, writing, transforming, and processing data. Mastering these tasks is the backbone of data manipulation, and once you do, you can easily handle any data-related job.

Data processing involves many tasks, including aggregations, data linking, and machine learning.

Databricks Utilizes Apache Spark for Data Processing.

Apache Spark, an open-source marvel, is at the heart of Databricks, making it a powerhouse for data processing. This connection is no coincidence, as Spark is the go-to data processing tool in big data, and the minds created Databricks behind Spark.

You might wonder why you should use Databricks when you can use Spark. The answer is simple: running Spark requires setting up a cluster of computers, each with its memory and multiple cores, working in tandem.

This distributed and parallel setup is essential for handling large data volumes and future scalability. However, managing clusters and fine-tuning Spark configurations can be a headache, diverting your focus from actual data processing.

That’s where Databricks comes in. It removes the hassle by allowing you to define your cluster preferences and handle everything else effortlessly. Clusters materialize when required and disappear when idle.

Spark comes pre-installed and configured with auto-scaling capabilities within the limits you set. This means less worrying about infrastructure and more time devoted to value-generating data processing.

The beauty of Databricks doesn’t end there. It optimizes both Spark and its clusters, ensuring superior speed and efficiency. It’s not just data processing; it’s data processing at its best. But here’s the real magic – Databricks transforms this potent core into a comprehensive data platform.

How is Databricks Unlike Regular Databases or Data Warehouses?

Data processing requires different tools depending on the task at hand. Databases and data warehouses are designed for quick responses to queries on smaller datasets. Databricks, however, is optimized for high-throughput data processing, making it an excellent choice for super-efficient transformations and calculations, especially as data scales up.

To further boost query performance, Databricks incorporates Photon, an engine that works seamlessly with Spark. Spark and Photon together cover the entire spectrum of data processing. However, there is a significant difference between Databricks and databases or data warehouses regarding how and where your data is stored.

Databricks Data Control: Your Storage, Your Way

A database or data warehouse processes your data using its query engine and stores it in its format. You can only access that data by using the database or data warehouse. And in some cases, once you put your data in there, you need to pay to read that data out.
‍
Databricks don’t store data. (Granted, there are some subtleties here. But this statement and the following holds when implementing Databricks using best practices.)
‍
Databricks reads data from storage and writes data to storage, but that storage is your own — depending on your cloud of choice, your data will be in Amazon S3, Azure Data Lake Storage Gen2 or Google Cloud Storage.
‍
Databricks doesn’t require a proprietary data storage format; it uses open-source formats and can also read from and write to databases. The choice is yours.
‍
The net result is that you always have full control of your data. You know exactly where it is and how it is stored. You’re not locked in either: if you want to access your data without using Databricks, then you can.

Databricks Blends Your Data Lake and Warehouse Into the Data Lakehouse.

Cloud storage is great for creating a data lake but needs more guarantees and robustness. Databricks Delta Lake addresses this by adding ACID compliance and transaction logs to ensure data operations are recorded and accessible in a familiar Parquet format.

It supports batch and real-time data, schema enforcement or modification, and ‘time travel’ to access older data versions. Databricks transforms your data lake into a data warehouse-like structure, offering both advantages, and this fusion is known as the ‘data lakehouse.’

While Spark and Delta Lake Play Vital Roles, Databricks Extends Beyond These Essential Components.

Databricks offers a wide range of features for data utilization, including Spark and Delta Lake. It allows users to create clusters with machine learning packages and GPUs and provides interactive notebooks for data scientists and ML engineers. Databricks Machine
