Snowflake comes with robust SQL support and boasts high availability and reliability. Snowflake is a cloud-based data platform that can be employed for various use cases, such as data warehouses, data lakes, or even unified data stores. What is the impact of GenAI on Data Engineering? Redshift ML helps build machine learning models through SQL and deploy them using AWS Sagemaker. Redshift Spectrum enables querying data located in S3 or other data lakes using the processing power of your Redshift cluster. Its federated query feature allows one to query external operational databases and join their data with Redshift to derive insights. RA3 instances permit the scaling of storage and performance independently.īeyond traditional warehouse features, Redshift offers many nice-to-have features. Customers should use RA3 for storage-intensive workloads and Dense Compute instances for performance-intensive workloads below 1 TB in size. Redshift provides two options for compute nodes: Dense Compute and RA3 instances. Compute nodes are worker nodes that come with their own processing power and memory, while leader nodes are responsible for communicating with external clients, developing execution plans, and communicating with the compute nodes. Under the hood, Redshift is a cluster comprising compute nodes and leader nodes. It can handle petabytes of data and still deliver fast query performance by using columnar data storage. Snowflake is maintenance-free, not requiring manual intervention to maintain query performance.ĪWS Redshift is a data warehouse that supports an SQL standard compatible with PostgreSQL. Redshift requires manual vacuum operation to maintain query performance. Snowflake scaling is done by increasing the virtual warehouse size or adding more clusters to the virtual warehouse, which takes tens of seconds to complete. Redshift scaling is done by adding more nodes to the existing cluster, which takes minutes to complete. The pricing structure also varies according to the selected cloud provider. Snowflake uses a tiered storage and compute structure with additional features available in higher tiers. For RA3 type of instances, the costs of storage and processing power are separate. For Dense Compute instances, the costs of storage and processing power are tied together. Redshift offers two kinds of cost structures. Snowflake supports Java, Python, Javascript, and SQL for UDFs. Redshift supports Lambda functions for implementing its UDFs, which helps it support UDFs written in any language or runtime supported by Lambda. Snowflake is completely serverless and does not require any node configuration. More recently Redshift has also launched a serverless version. Redshift requires some configuration and setup nodes and instance types. Snowflake is a cloud-agnostic offering that can work with all three major cloud service providers: Google Cloud, Microsoft Azure, and Amazon. Redshift is an offering from AWS that tightly integrates with AWS. The two platforms accomplish this objective differently because of the approach in their underlying design and marketing visions. Redshift and Snowflake are cloud-based data platforms that employ massive parallel processing to help ingest and process huge volumes of data. This article will discuss the key differences and similarities between Snowflake and Redshift. Being cloud-agnostic, you can run Snowflake on any cloud – Amazon Web Services (AWS) Google Cloud Platform (GCP), and Microsoft Azure (Azure). Snowflake is a cloud-agnostic, serverless data platform that supports many workloads, including data lakes, data warehouses, and machine learning. AWS Redshift started out as a cloud-based data warehouse service and has since been moving towards becoming a data platform by adding more features, such as data lake implementation support and an independent query engine. They provide ready-to-use solutions.ĪWS Redshift and Snowflake are two popular platforms in the cloud-based data platform space. Fully managed cloud-based data platforms help organizations focus on their core business problems without getting distracted by the herculean amount of effort required to maintain the infrastructure.
