Amazon Redshift ETL Tools: Pros, Cons, Features, Pricing

CEO, Portable

Amazon Redshift is one of the most popular cloud data warehouses, but it's only as valuable as the data it contains. And to do that, you'll need to have an effective ETL pipeline in place.

Today, we'll cover strategies for using ETL on Redshift, which tool is best for different use cases, and more.

Amazon Redshift: Data Warehouse Overview

  • Amazon Redshift is a fully managed cloud-based data warehouse. It's part of Amazon Web Services (AWS) and offers essentially unlimited scaling for big data at an affordable price.

  • Your processes on Redshift are organized as nodes organized into clusters, with each cluster running on an engine.

  • Every cluster has a leader node and anywhere from one to 128 computing notes, determined as either dense storage (with HDD) or dense compute (SSD).

  • Redshift uses column-oriented, OLAP (online analytic processing ) databases, making it a great tool for analytics and business intelligence.

  • For teams that need OLTP (online transaction processing), Amazon RDS is a better option.

  • You can interact with Redshift data using the Redshift Data API, a web interface like Amazon Redshift Query Editor V2, or a command-line tool like Amazon Redshift RSQL. 

Why Redshift is a smart choice for ETL

Redshift has several competitors in the data warehouse space, including Snowflake and Microsoft Azure Synapse Analytics. But there are a few reasons why AWS Redshift has remained an industry leader for almost a decade.


  • Redshift prices start at around $0.25/hour but vary depending on region, compute density, vCPU, and more.

  • Redshift offers big discounts for Reserved Instances.

  • Redshift offers a two-month free trial for new users.

Key features

  • Most likely the most affordable option on the market, with zero upfront cost, generous free trial volumes, and huge savings for paying for reserved nodes in advance.

  • Speeds up to 10x as fast as competitors, with under-the-hood innovations like query distribution, machine learning optimizations, and massively parallel processing architecture.

  • Granular security permissions including access management, cluster encryption, SSL connections, and more.

  • Near-infinite capacity to scale, from a few gigabytes to a few petabytes.


  • Easy-to-use platform that relies on basic SQL.

  • Deep integration in the AWS ecosystem, with seamless connections to tools like Athena, Amazon S3, Database Migration Service, and many more.

  • AWS Lambda Utility Runner to automate some monitoring processes.


  • Doesn't separate storage and computing like Snowflake and BigQuery, resulting in delays.

  • Only supports AWS cloud infrastructure.

  • Limited support for JSON functions in SQL.

  • Elasticity is limited to "Elastic Resize" feature, which is limited and requires downtime.

  • Large administrative overhead with granular settings for everything, instead of default settings that work in most use cases.

Who is Redshift best suited for?

Redshift is a cost-effective platform that's best for enterprise clients with precise, granular needs and the technical know-how to implement those needs themselves.

Should you configure your own Redshift ETL pipeline?

Amazon Redshift isn't an ETL tool but has built-in ETL capabilities.

It's also compatible with several ETL tools, including others in the AWS ecosystem and third-party tools.

You can use Redshift for both ETL and ELT, but as a modern data warehouse, it's best served with ELT workflows. This process---extract, load, transform---leverages Redshift's cloud scalability for data transformations.

Native ETL in AWS pipeline may sound tempting, but it's not for the faint of heart. You'll own the entire system and completely control each step, but there are detailed recommendations to follow.

These include:

  • Using a single COPY command instead of several when loading multiple files into a target table

  • Using workload management to define queues dedicated to separate workloads

  • Using BEGIN and END statements to execute several transformations in each commit, rather than sequential steps on transformed data

  • Because Redshift doesn't automate as many maintenance processes as competitors like BigQuery, you'll need to include these best practices in your scripts.

  • Most data teams want to focus their time on analytics, not managing custom-built ETL processes. If that sounds like your team, you'll want to choose a third-party tool.

How to choose the right Redshift ETL tool

AWS has several ETL and data pipeline tools including AWS Glue, AWS Data Pipeline, and AWS Kinesis. Each has a different use case, but they're not necessarily the best options for most businesses.

Redshift's popularity means there are dozens of ETL tools from third parties, which are usually more flexible than AWS tools. Here's what to look for.

Data sources

Any tool can load data from major sources like Oracle or MySQL databases. But what about the less-popular apps that deliver mission-critical data? Look for a tool that integrates all the data sources you'll need, not just the biggest ones.


Your data workloads in a few years will be different than they are today. Will your ETL tool adapt? Look for a tool that makes it easy to connect new data sources and destinations.

Designed for Redshift

Just because a data integration tool is compatible doesn't mean it's built for the unique optimizations Redshift offers. Look for a tool that's designed to leverage the speed built into Redshift's unique architecture.

Customer Support

When something goes wrong, you need a team who's able to help. API changes and other connector-breaking changes are a common occurrence, so look for a tool with a team that responds quickly.

Top 5 Redshift ETL tools

  1. Portable
  2. AWS Glue
  3. Stitch
  4. Hevo
  5. Blendo

1. Portable

Portable is the most ideal Redshift ETL tool for hard-to-find data sources. It already has 300+ long-tail ETL connectors, with more being delivered every month---all focused on long-tail apps that the big platforms ignore.

Portable also delivers new connectors within days or even hours, at no extra cost. If you've started using a new app and need a custom Redshift connector, the Portable team can have it ready to use in less time than it'd take to build it yourself.

And maintenance, alerting, and reporting are handled for you. That means if your app's API changes, the Portable team will make the necessary adjustments, so it keeps working. No more missing data because a connector broke without warning.


  • Portable offers a free plan for manual data workflows with no caps on volume, connectors, or destinations.

  • For automated data flows, Portable charges a flat fee of $200/month.

  • For enterprise requirements and SLAs, contact sales.

Key features

  • 300+ data connectors meant for long-tail applications.

  • New data source connectors developed within days or hours at no extra cost.

Runner-up Redshift ETL tools

We couldn't fit every Redshift data tool in this list. Here are some other ETL tools that we didn't feature, but that might work based on your data needs.

AWS Data Pipeline and AWS Kinesis

These are two other AWS data tools, in addition to Glue. AWS Data Pipeline helps import data, but doesn't have as many transformation options as Glue. Kinesis is designed for real-time and streaming data.


Fivetran supports 160+ data sources, mostly focused around major applications. It's a robust platform designed for enterprises.

Integrate is a codeless platform with 200+ built-in integrations, focused around eCommerce. It uses templates to speed up new data integrations.


Matillion is an all-in-one ELT data warehouse tool that supports 110+ data sources. It offers cloud-based and on-premise deployments.

Redshift ETL: The Bottom Line

Redshift is a deservedly popular choice for data warehousing. It's fast, scalable, and affordable---and integrates with the AWS ecosystem better than anything else out there. With the right ETL system for importing Amazon Redshift data, you'll build a robust and effective data analytics solution.

But Redshift's built-in ETL tools leave much to be desired. They'll increase the amount of time and work your data team has to spend collecting and transforming data. Portable eliminates that busywork and lets your team focus on insights, not troubleshooting.
