runs in tandem with Amazon Redshift, while Athena is a standalone for stored in
With , you have control over resource provisioning, while in the case of Athena, allocates resources automatically.
The performance of Redshift depends on your resources and of , while the performance of Athena only depends on S3
can be more consistent performance-wise while querying in Athena can be slow during peak hours since it runs on pooled resources.
is more suitable for running large, , while Athena is more suited for simplifying
needs cluster management, while Athena allows for a truly architecture.
At a quick glance, and Athena seem to offer the same functionality — query of data in using . You don't need to maintain any infrastructure, which makes them incredibly cost-effective. However, the two differ in their functionality. Let's take a closer look at the differences between and .
Amazon Redshift. The service allows data analysts to run queries on data stored in S3. It makes it possible, for instance, to join data in with data stored in Amazon Redshift to run . is an extension of

Functionality and Performance Comparison for Redshift Spectrum vs. AWS Athena
Both the services use for managing . They use virtual tables to analyze data in . However, in the case of Athena, it uses 's directly to create virtual tables. With , on the other hand, you need to configure for each .
A key difference between and Athena is resource provisioning. In the case of Athena, the Amazon Cloud automatically allocates resources for your query. You do not have control over resource provisioning. Thus, performance can be slow during peak hours. When using Spectrum, you have control over resource allocation since the size of resources depends on your . Thus, if you want extra-fast results for a query, you can allocate more to it when running .
and are compatible with , the platform provided as a part of Amazon’s . You can use as the repository for , which serves as a trusted data storage across your network.
Amazon recommends that users upgrade their internal data catalog with to , which can help cost and performance in the long term through improved capabilities. These include maintained scheme visioning and capabilities of converting data into for faster analytics . According to tests, formats have shown cost-effectiveness and faster performance compared to row-based .
Additionally, several can access the same simultaneously. However, you can only analyze data in the same region.
Arrange for a call with Integrate.io to discover the most suitable to your data management processes.
Athena has prebuilt that let you from sources other than . Athena can connect to Redis, Elasticsearch, HBase, DynamoDB, DocumentDB, and CloudWatch. If you want to analyze data stored in any of those databases, you don't need to load it into S3 for analysis. You can run your queries directly in Athena.
Redshift uses to run the same queries on historical data and live data. More importantly, with , you can perform complex transformations on data stored in external sources before loading it into Redshift. ETL is a much more secure process than ELT, especially when sensitive information is involved.
and provide varying according to specific data management needs in . For instance, you might consider for VPCs (virtual private clouds).
expands the analytic powers within Amazon Redshift. As such, you can effortlessly apply for added data management implementations. For instance, can help improve the interoperability of by providing accessibility to multiple formats outside Amazon Redshift.
With AWS Redshift Spectrum, you can effectively optimize your querying and scaling process across nodes that optimize your networks' performance.
Essentially, enables you to your as a service. Running multiple operations outside of Redshift reduces the computational load on Redshift, ultimately improving the , performing markedly better than native Redshift in some .
allows you to share across Redshift clusters by creating external tables. Querying each table with reduces the risk of data duplication while providing a consistent user view across the shared data. These processes can help streamline and multi-tenant involving multiple separate data clusters.
serves as an efficient solution for analyzing unstructured and structured , such as , , and formats that include Apache ORC. With , you can readily generate insightful reports by integrating with leading business intelligence tools to provide detailed . Additionally, you can conveniently integrate with a data visualization tool like Amazon Quicksight that offers an improvement to standard database .
You can apply in from , a cloud platform that makes it cost-effective to manage large-scale, highly distributed data frameworks such as and Hadoop. The flexibility of can provide your systems with efficient management of data streaming, machine learning, data transformations, and graph analytics.
Since works well with many similar as , you can query your multiple in a frictionless process.
vs. Athena Cost Comparison
Both services follow the same structure. You only pay for the queries you run. The total cost is calculated according to the you scan per query. The cost of running queries in and Athena is $5 per TB of scanned data.
It is important to note that you need Redshift to run . If you are not an Amazon Redshift customer, running together with Redshift can be very costly.
More importantly, consider the cost of running Amazon Redshift together with . The cost of running Redshift, on average, is approximately $1,000 per TB, per year.
vs. : Which One to Choose?
The two services are very similar in how they run queries on data stores in using . For example, each solution queries with S3 through standard SQL, and you will need to your layers to the performance of both querying systems. However, to decide between the two, consider the following factors:
1) Are You an Existing Redshift Customer?
For existing Redshift customers, Spectrum might be a better choice than Athena. They can leverage Spectrum to increase their capacity without scaling up Redshift. It can help them save a lot of dollars.
For example, you can store infrequently used data in and frequently stored data in Redshift. Doing so reduces the size of your and, consequently, your annual bill while you manage efficiently.
You can get started on in a few easy steps. Firstly, you will need to create an role for Amazon Redshift, which authorizes your . You will need to associate the role with your Amazon , which provides access to the external data catalog and .
It is important, though, to keep in mind that you pay for every query you run in Spectrum. If your team of analysts is frequently using to run queries, calculate the cost vis-a-vis storing your entire data in .
If you are not a Redshift customer, Athena might be a better choice. You don't need to maintain any clusters with Athena. You can build a truly architecture.
2) Compatibility With Your Analytic Tools
Before you choose between the two , check if they are compatible with your preferred analytic tools. Both the services use OBDC and JBDC drivers for connecting to external tools.
3) Budget Considerations for Improved Performance
Because has a generally more consistent performance compared to since it does not tap on a pool of shared data resources like , it might require a higher cost. Specifically, you might need to expand your core to accommodate the increased usage if needed.
