Amazon Redshift

What differentiates Amazon Redshift from other similar products?

The easy way to deploy and resize a cluster. The auto recommendations to improve performance even Redshift does changes at table level to improve performance i.e distribution type and encode.

What is your favorite aspect of this product?

Recently we starting to use ML features and it is great because you can create different types of models based just in a query and then predict in your queries. You do not need spend lot of time in development hours.

What do you dislike most about this product?

It would be nice to have the ability to resize the cluster by selecting specific characteristics such as disk size, memory, etc. and not just selecting a node type

What recommendations would you give to someone considering this product?

Amazing cloud data warehouse with bunch of features like ML and json functions. The best to use Redshift it is the possibility to integrate with the AWS ecosystem like S3 to query files directly.

What differentiates Amazon Redshift from other similar products?

For any startup or an enterprise company Amazon Redshift can give very quick start with setting up data warehouse . It is very performant from the get go , so not much expertise required. Also provide many unique features like giving query runtime, killing query in advandse with wlm rules based on joins / runtime etc

What is your favorite aspect of this product?

Ease of use with Amazon Redshift is very high. And it is very performant also . Using any other system without technical expertise will require decent amount of fine tuning and efforst and management

What do you dislike most about this product?

The concurrency can be issue , especially in organizations where very large number of queries are executed . Also it is less flexible in terms of working with the modern data formats like delta , druid etc

What recommendations would you give to someone considering this product?

If you lack technical expertise or a big team of big data engineers , then using amazon redshift is one of the best decisions you can make

What differentiates Amazon Redshift from other similar products?

Redshift is a fully managed cloud data warehouse, meaning AWS handles infrastructure, backups, scaling, and patching. Unlike traditional on-premises warehouses (like Oracle Exadata or Teradata), you don’t need to worry about hardware, OS, or software maintenance Redshift uses a distributed, columnar architecture with Massively Parallel Processing (MPP). This allows it to process large volumes of data efficiently by splitting queries across multiple nodes. Many competitors like MySQL or PostgreSQL struggle with analytics at this scale

What is your favorite aspect of this product?

My favorite aspect of Amazon Redshift is its scalability and performance in handling large-scale data analytics. The combination of columnar storage, MPP architecture, and features like concurrency scaling makes querying massive datasets fast and efficient. I also appreciate its tight integration with the AWS ecosystem, which simplifies ETL, security, and data-sharing workflows, making it easier to manage complex analytics pipelines.

What do you dislike most about this product?

The main drawback I’ve noticed is the lack of enforcement for data constraints like unique keys or foreign keys, which can make maintaining data integrity more challenging. Additionally, handling semi-structured data (like JSON in SUPER columns) is limited, and achieving optimal performance sometimes requires manual tuning of sort keys, distribution keys, and compression. These aspects can make Redshift less flexible compared to some newer cloud data warehouses.

What recommendations would you give to someone considering this product?

I would recommend: Understand your data and queries – plan your distribution keys, sort keys, and compression carefully to optimize performance. Use Redshift’s integration with AWS services – leverage S3, Glue, Kinesis, and IAM for seamless ETL, data ingestion, and security. Be aware of limitations – Redshift does not enforce constraints and has some restrictions with semi-structured data, so plan ETL pipelines and data validation accordingly.
