What is Amazon Athena?<\/strong>
\n\"ama\"<\/a><\/p>\n

Athena acts as a server-less query service. It\u2019s entire design purpose is built around affording you the ability to have large quantities of Amazon S3-stored data quickly analyzed through Standard SQL.Amazon describes Athena as a serverless interactive query service. Athena accesses data directly from S3 with setting up any servers, frameworks, clusters or other tools other than getting the data loaded to S3.<\/p>\n

Athena<\/strong><\/p>\n

— Rapid query results without having to worry about tuning queries or optimizing database structures.<\/p>\n

— Amazon S3 stores the data, there is no need for businesses to invest in physical IT infrastructure to query and store their information.<\/p>\n

— an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL.<\/p>\n

— easy to use. Simply point to your data in Amazon S3, define the schema, and start querying using standard SQL.<\/p>\n

— no need for complex ETL jobs to prepare your data for analysis. This makes it easy for anyone with SQL skills to quickly analyze large-scale datasets.<\/p>\n

— quickly query your data without having to setup and manage any servers or data warehouses<\/p>\n

— all your data in S3 without the need to set up complex processes to extract, transform, and load the data (ETL).<\/p>\n

— underlying data store, making your data highly available and durable.<\/p>\n

— quick, ad-hoc querying but it can also handle complex analysis, including large joins, window functions, and arrays. Amazon Athena is highly available<\/p>\n

— no infrastructure to manage, and you pay only for the queries that you run.<\/p>\n

Athena stand out and easy to use for big and small companies, especially if they are already using or are planning to use AWS S3.<\/p>\n

Amazon Athena Work<\/strong>
\n— Athena don\u2019t want to waste inordinate amounts of time with scanning, loading, and indexing data sets.<\/p>\n

— The solution is Point-and-shoot functionality.<\/p>\n

— Point Athena to the data in question within your Amazon Simple Storage Service (S3).<\/p>\n

— Run your fields and queries, and then Athena returns the results within moments.<\/p>\n

— Athena simply works quietly and efficiently to parallelize your query<\/p>\n

Amazon Athena Benefits<\/strong><\/p>\n

— Athena is server less built-in query editor allows you to point your data in Amazon S3, and prepare for analysis without the need for ETL processes.<\/p>\n

— Open Source Design includes ANSI SQL support, and plays nice with standard formats including ORC, Parquet, JSON, and CSV.<\/p>\n

— Only Pay what you run you only open up your wallet for the queries that you need to run.<\/p>\n

— Faster Execution\u00a0lightning-quick query performance through automatically executing all queries in parallel.You can expect results in mere seconds!<\/p>\n

ETL (Extraction, Transformation, Loading)<\/strong><\/p>\n

— Extracts data from homogeneous or heterogeneous data sources<\/p>\n

— Transforms the data for storing it in proper format or structure for querying and analysis purpose<\/p>\n

— Loads it into the final target (database, more specifically, operational data store, data mart, or data warehouse)<\/p>\n

Encounters:<\/strong><\/p>\n

— Query execution time at Athena can vary wildly.<\/p>\n

— scanning around 15 GB of data of anywhere from 60 seconds to 2500 seconds (~40 minutes)<\/p>\n

— scanned around 500 MB in 1800 seconds (~30 minutes)<\/p>\n","protected":false},"excerpt":{"rendered":"
