Designed to simplify the querying process, Athena allows users to analyze data stored in Amazon S3 using standard SQL. Unlike traditional databases, Athena eliminates the need for infrastructure setup or server maintenance, making it an excellent choice for ad-hoc data analysis.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Athena leverages Presto, a distributed SQL query engine, to execute queries. It supports multiple data formats, including CSV, JSON, Parquet, and ORC, providing users with flexibility in how they store and query their data. Additionally, Athena employs a schema-on-read approach, meaning users can define the data schema at the time of query execution rather than during data ingestion.<\/span><\/p>\n<h3>Key Features of AWS Athena<\/h3>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Serverless Architecture<\/b><span style=\"font-weight: 400;\">: One of Athena\u2019s most appealing features is its serverless nature.
