Sentiment score
7.4
Teradata is praised for its scalability, speed, and flexibility, despite some complexity and cost challenges in cloud environments.
The scalability part needs improvement as the sizing requires trial and error.
Snowflake is very scalable and has a dedicated team constantly improving the product.
The billing doubles with size increase, but processing does not necessarily speed up accordingly.
This expansion can occur without incurring downtime or taking systems offline.
Scalability is complex as you need to purchase a license and coordinate with Teradata for additional disk space and CPU.

Sentiment score
7.4
Amazon Redshift is stable with minor scaling challenges, appreciated AWS support, and noted visibility concerns versus Snowflake.
Sentiment score
8.2
Snowflake is praised for stability and reliability, with users noting excellent performance, quick issue resolution, and robust architecture.

Room For Improvement

Amazon Redshift users struggle with data management, pricing, performance, integration, UI support, and compatibility with various data types.
Snowflake users seek improved UI, pricing transparency, analytics, integrations, AI features, and enhanced support, ETL, and machine learning capabilities.
Teradata users seek better transaction processing, enhanced scalability, modern interface, cloud focus, advanced analytics, and improved support and documentation.
Integration with AI could be a good improvement.
They should bring the entire ETL data management process into Amazon Redshift.
Enhancements in user experience for data observability and quality checks would be beneficial, as these tasks currently require SQL coding, which might be challenging for some users.
Cost reduction is one area I would like Snowflake to improve.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
 

Setup Cost

Amazon Redshift offers competitive pricing with scalable costs, ideal for large enterprises, though not as economical for smaller companies.
Snowflake's pricing offers flexibility but can be unpredictable and expensive compared to Redshift or BigQuery, with room for transparency improvements.
Teradata's high cost is justified by its superior performance, competitive total ownership costs, and flexible pricing models.
It's a pretty good price and reasonable for the product quality.
The cost of technical support is high.
The pricing of Amazon Redshift is expensive.
Snowflake's pricing is on the higher side.
Snowflake lacks transparency in estimating resource usage.
Initially, it may seem expensive compared to similar cloud databases, however, it offers significant value in performance, stability, and overall output once in use.
Teradata is much more expensive than SQL, which is well-performed and cheaper.
 

Valuable Features

Amazon Redshift offers scalable, efficient, and secure data warehousing with fast processing, AWS integration, and flexible configurations for analytics.
Snowflake excels in scalable, secure data processing with fast queries, multi-format support, and seamless third-party integration for AI/ML.
Teradata offers efficient, scalable data management with fast query performance, robust security, automation, and cloud flexibility for businesses.
Scalability is the best feature of Amazon Redshift. Amazon Redshift handles scalability automatically, so we do not need to scale up or down; it is all managed by Redshift.
Scalability is also a strong point; I can scale it however I want without any limitations.
Amazon Redshift's performance optimization and scalability are quite helpful, providing functionalities such as scaling up and down.
The independence of the compute and storage within Snowflake is key.
One key feature is the separation of compute and storage, which eliminates storage limitations.
The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems.

Featured Reviews

Sriram-Natesan - PeerSpot reviewer
The ability to create a lot of views or materialized views is beneficial
Improvement in the immediate response and the process of getting into a call could be helpful. We have had to wait for at least twenty-four hours to get a call and then wait for a couple more hours for a solution. Improved connectivity to different BI tools and already published connectors for major tools in AWS could enhance the service.
Snehasish Das - PeerSpot reviewer
Transformation in data querying speed with good migration capabilities
Snowflake is a data lake on the cloud where all processing happens in memory, resulting in very fast query responses. One key feature is the separation of compute and storage, which eliminates storage limitations. It also has tools for migrating data from legacy databases like Oracle. Its stability and efficiency enhance performance greatly. Tools in the AI/ML marketplace are readily available without needing development.
