What is Amazon Athena good for?
Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. Athena is easy to use.
Is Athena secure?
Athena supports several security features, including AWS Key Management Service (AWS KMS) for encryption, and AWS Identity and Access Management (IAM) for access control. You can also use AWS CloudTrail to monitor Athena and analyze security event trends using Amazon QuickSight.
What permissions does Athena?
The permissions required to run Athena queries include the following:
- Amazon S3 locations where the underlying data to query is stored.
- Metadata and resources that you store in the AWS Glue Data Catalog, such as databases and tables, including additional actions for encrypted metadata.
- Athena API actions.
Is Amazon Athena fully managed?
Amazon Athena uses a managed Data Catalog to store information and schemas about the databases and tables that you create for your data stored in Amazon S3. In regions where AWS Glue is available, you can upgrade to using the AWS Glue Data Catalog with Amazon Athena.
What is Athena used for?
Amazon Athena is a service that enables data analysts to perform interactive queries in the web-based cloud storage service, Amazon Simple Storage Service (S3). Athena is used with large-scale data sets. Amazon S3 is designed for online backup and archiving of data and applications on Amazon Web Services (AWS).
How much data can Athena handle?
Athena database limits 3. Athena restricts each account to 100* databases, and databases cannot include over 100* tables. *Note, recently Athena has increased this to 10K databases per account and 200K tables per database.
Is Athena accessible from Internet?
Athena is a serverless tool: you don’t set up any Athena instance inside a VPC, and there’s no Security Group to filter out unwanted traffic. Just like S3, Athena must be accessed over the Internet.
Does Athena need a VPC?
With this feature, you can submit your queries to Athena securely without requiring an Internet Gateway in your VPC. You can create an interface VPC endpoint to connect to Athena using the AWS console or AWS Command Line Interface (AWS CLI) commands. For more information, please see Creating an Interface Endpoint.

Because Workgroups act as resources, you can use resource-based policies to control access to a Workgroup.
What is the difference between Athena and RDS?
Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. On the other hand, Amazon RDS for Aurora is detailed as “MySQL and PostgreSQL compatible relational database with several times better performance”.
Which is faster Athena or redshift?
A highly optimized Redshift cluster with sufficient compute resources will most likely return results faster than the same query in Athena.
Can Athena be used as a database?
Athena is not a database but rather a query engine. This means that: Compute and storage are separate: databases both store data in rest, and provision the resources needed in order to perform queries and calculations.
What are the weaknesses of AWS Athena?
Some of the common Amazon Athena limits are technical limitations that include query limits, concurrent queries limits, and partition limits. AWS Athena limits performance, as it runs slowly and increases operational costs.

What port does Athena use?
port 444
Athena’s streaming API uses port 444 to stream the query results.
How do I connect Athena to RDS?
Configure RDS as Data Source. You configure PostgreSQL RDS instance as the data source for Amazon Athena so that you can query RDS data from the Athena Query Editor. Goto Athena Management console and click on Data sources link. On the next screen, click on the Connect data source button.
Why is Athena so important?
Athena became the goddess of crafts and skilled peacetime pursuits in general. She was particularly known as the patroness of spinning and weaving. That she ultimately became allegorized to personify wisdom and righteousness was a natural development of her patronage of skill.
