In the event you’ve labored with knowledge science currently, you could have heard about Snowflake and Databricks and the way they relate to one another.
In the event you’re unsure what precisely these instruments are and which one to make use of, you then’ve come to the proper place. This text will focus on what they’re, examine and suggest every one for the use case the place it really works finest.
What’s Databricks?
Databricks is a complete knowledge platform that extends Apache Spark. It’s created by the makers of Apache Spark and utilized by a few of the greatest firms like HSBC, Amazon, and so forth.
As a platform, Databricks supplies a approach to work with Apache Spark, Delta Lake, and MLFlow to assist prospects clear, retailer, visualize, and use knowledge for machine studying functions.
It’s open supply software program, however there’s a cloud-based managed possibility out there as a subscription service. Like Snowflake, it follows the lakehouse structure that mixes the advantages of information warehouses and knowledge lakes.

What’s Snowflake?
Snowflake is a cloud-based knowledge warehousing system. It really works as a pay-per-use service the place you’re billed for the assets you utilize.
Considered one of Snowflake’s promoting factors is that billing for computer systems and storage is separate. Which means that firms that want numerous space for storing, however little computing energy, do not need to pay for the computing energy they do not want.
The platform additionally features a customized SQL question engine designed to run natively within the cloud. Snowflake runs on prime of the favored cloud suppliers: Google Cloud, Amazon AWS and Microsoft Azure.
Similarities between Snowflake and Databricks
Each Databricks and Snowflake are knowledge lakehouses. They mix the options of information warehouses and knowledge lakes to supply the most effective of each worlds by way of knowledge storage and computing.
They decouple their storage and computing choices in order that they scale independently. You should use each merchandise to create dashboards for reporting and evaluation.
Variations between Snowflake and Databricks
| Facet | Databricks | Snowflake |
| Structure | Databricks makes use of a two-tier structure. The underside layer is the info airplane. The first duty of this layer is to retailer and course of your knowledge. The storage is dealt with by the Databricks file system layer that sits on prime of your cloud storage: AWS S3 or Azure Blob Storage. A cluster managed by Apache Spark handles the processing. The topmost layer is the Management Airplane layer. This layer incorporates workspace configuration information and Pocket book instructions. |
Snowflake’s structure may be considered three layers. The bottom layer is the info storage layer. That is the place the info resides. The Question Processing layer is the center layer. This layer consists of ‘digital warehouses’. These digital warehouses are impartial compute clusters of various compute nodes that compute queries. The highest layer consists of Cloud Providers. These companies handle and produce collectively the opposite components of Snowflake. They supply features equivalent to authentication, infrastructure administration, metadata administration and entry management. |
| Scalability | Databricks robotically scales primarily based on load by including extra staff to clusters whereas decreasing the variety of staff on underutilized clusters. This ensures that workloads run shortly. | Snowflake robotically scales up or down pc assets to carry out numerous knowledge duties, equivalent to loading, integrating, or analyzing knowledge. Whereas nodes can’t be resized, clusters can simply be scaled up or all the way down to a most of 128 nodes. As well as, Snowflake robotically supplies extra compute clusters when a cluster turns into overloaded and distributes the load between the 2 clusters. Storage and computing assets may be scaled independently. |
| Safety | With Databricks, you’ll be able to create a Digital Non-public Cloud together with your cloud supplier to run your Databricks platform. This offers you extra management and manages your cloud supplier’s entry. As well as, you need to use Databricks to handle public entry to cloud assets via community entry management. It’s also possible to create and handle encryption keys for added safety. For API entry, you’ll be able to create, handle, and use private entry tokens. |
Snowflake gives related safety choices to Databricks. This contains managing community entry by way of IP filters and block lists, setting idle person session timeouts for when somebody forgets to sign off, utilizing robust encryption (AES) with rotated keys, role-based entry management to knowledge and objects , multi-factor authentication at login, and single sign-on by way of federated authentication. |
| Storage | Databricks shops knowledge in any format. The Databricks platform primarily focuses on knowledge processing and software layers. Because of this, your knowledge may be wherever: within the cloud or on-premises. |
Snowflake shops knowledge in a semi-structured format. For storage, Snowflake manages the info layer and shops the info in Amazon Net Providers or Microsoft Azure. |
| Integrations | Databricks integrates with the preferred knowledge acquisition integrations. | Snowflake additionally integrates with these in style knowledge assortment integrations. For Snowflake, the oldest instrument, traditionally most instruments have been constructed for it. |
Utilization eventualities for Databricks
Databricks are most helpful when performing knowledge science and machine studying duties equivalent to predictive analytics and advice engines. As a result of it’s extensible and may be fine-tuned, it is suggested for companies coping with bigger knowledge workloads. It supplies a single platform for processing knowledge, analytics and AI.
Utilization eventualities for Snowflake
Snowflake is finest used for Enterprise Intelligence. This contains utilizing SQL for knowledge evaluation, reporting on the info, and creating visible dashboards. It’s good for knowledge transformation. Machine Studying capabilities are solely out there via extra instruments equivalent to Snowpark.
Final phrases
Each platforms have their strengths and completely different function units. Primarily based on this information, it ought to be simpler to decide on a platform that matches your technique, knowledge workload, volumes and desires. As with most issues, there is no such thing as a proper or flawed reply, simply the reply that most accurately fits you.
Subsequent, try good assets to study Huge Knowledge and Hadoop.
