When it comes to querying massive datasets, having the right tool in your arsenal can make all the difference. AWS offers two powerful query engines, Athena and Presto, each with its own strengths and capabilities. In this blog post, we’ll explore the key differences between AWS Athena vs. Presto and provide a detailed comparison table to help you make an informed decision for your data querying needs.
AWS Athena: A Quick Overview
Amazon Athena is an interactive query service that allows you to analyze data stored in Amazon S3 using standard SQL queries. It’s a serverless and fully managed service, which means you can focus on querying your data without the need for infrastructure setup or management. Athena is designed for ad-hoc querying and is well-suited for users familiar with SQL.
Presto: An Overview
Presto, on the other hand, is an open-source distributed SQL query engine that can connect to various data sources, including Hadoop, relational databases, and cloud storage. Presto is known for its speed and versatility in handling complex queries on large datasets. While it can be self-hosted, there are also managed Presto services available, such as AWS EMR (Elastic MapReduce).

Comparison Table
Let’s delve into a detailed comparison of AWS Athena and Presto across various dimensions:
| Aspect | AWS Athena | Presto |
|---|---|---|
| Purpose | Interactive querying of data in Amazon S3 with SQL. | Distributed SQL query engine for various data sources. |
| Ease of Use | User-friendly with standard SQL; minimal setup. | SQL-like syntax but may require more configuration in some cases. |
| Data Sources | Queries data in Amazon S3; ideal for S3-centric workloads. | Connects to a wide range of data sources, including cloud storage. |
| Scalability | Scalable but may require optimization for large queries. | Highly scalable and designed for complex queries on large datasets. |
| Performance | Performance varies based on query complexity and data size. | Known for fast query execution, especially with distributed setups. |
| Complex Transformations | Limited data transformation capabilities within queries. | Supports complex data transformations and joins, suitable for ETL. |
| Cost Model | Pay per query and data scanned; cost-effective for ad-hoc querying. | Typically self-hosted, so costs include infrastructure management. |
| Real-time Processing | Not designed for real-time processing; suitable for batch queries. | Primarily suited for batch processing but can handle real-time with setup. |
| Ease of Management | Fully serverless; no infrastructure management needed. | Requires setup, configuration, and management, unless using managed services. |
| Use Cases | Ideal for on-demand querying and analysis of S3 data. | Suited for complex analytics, including data lakes and data warehouses. |
Choosing between AWS Athena and Presto depends on your specific data querying and processing needs. If you primarily work with data stored in Amazon S3 and require an easy-to-use, serverless solution for ad-hoc querying, AWS Athena is an excellent choice.
On the other hand, if you deal with diverse data sources, complex analytics, and require high performance, Presto may be the better fit. Presto’s distributed nature and versatility make it a powerful tool for large-scale data processing.

Here are some FAQS based on AWS Athena and Presto
- Is Presto the same as Athena?
- No, Presto and Athena are not the same. They are distinct query engines with some similarities in their capabilities but different architectures and use cases.
- Is AWS Athena based on Presto?
- While AWS Athena and Presto share some similarities in query syntax and capabilities, Athena is not based on Presto. Athena is a separate AWS service designed for querying data in Amazon S3, while Presto is an open-source distributed SQL query engine.
- What is the difference between Presto EMR and Athena?
- Presto EMR (Elastic MapReduce) is a version of Presto that can be run on AWS EMR clusters, while Athena is a fully managed serverless query service by AWS. The main difference lies in management and deployment; Athena requires no infrastructure management, while Presto EMR involves configuring and managing EMR clusters.
- Is Athena built on top of Presto?
- Athena is not built on top of Presto. While both query engines share similar goals of enabling SQL-based querying of data, Athena is a proprietary AWS service designed to query data in Amazon S3, while Presto is an open-source project developed by the Presto Software Foundation.
It’s worth noting that some organizations may choose to use both tools in their data processing pipelines, leveraging Athena for quick S3-based queries and Presto for complex analytics on various data sources.
Ultimately, the choice should align with your specific use cases, data sources, and performance requirements. Evaluating your needs thoroughly will help you determine which query engine, whether it’s AWS Athena or Presto, is the best fit for your data analysis tasks.
