Amazon Athena or else AWS Athena is generally a query service that is highly interactive and will directly help to analyze the data in Amazon S3 with the help of standard SQL. Users can also have an exact point of Athena in Amazon S3 where your data is stored and is also currently using standard SQL for running various commands of ad-hoc and acquire the results in just a few seconds of time with certain actions in the AWS Management Console. There is no particular infrastructure for managing or else setting up of AWS Athena as it is serverless. The users will be paying for the queries that only you run.
With the help of AWS Athena, the results will be displayed in a fast manner as it scales in an automatic way and parallel execution of queries will be done so that it takes less time for even with large data sets and queries that are complex as well.
AWS Athena helps the users to analyze all types of data such as structured, unstructured or else semi-structured which will be automatically stored in Amazon S3. Some of the examples for the respective AWS Athena are JSON, CSV or else columnar data formats like Apache ORC and Apace Parquet. Without any requirement of aggregate or else load the data into the AWS Athena, it can be directly used for running the ad-hoc queries with the help of ANSI SOL. In a bid to offer tenacious metadata store for your required amount of data in Amazon S3, this AWS Athena can also integrate with the AWS Glue Data Catalog.
Based upon the Central metadata store throughout the AWS account, AWS integration with ETL and the AWS Glue data discovery features, this process will help you to create query data and tables on the required purpose. In an order to have a data visualization with ease, this AWS Athena also integrates with AWS QuickSight. The named queries can also be created with the help of AWS Cloud Formation and run the queries in Athena with no-time. In such process, the named query will generally map with another query and will able to call the plenty of queries by taking the name as its reference.

Users can easily access AWS Athena by taking the help of AWS Management console by having a connection with JDBC using the Athena CLI or else Athena API. If the users want to use it with CLI, then first install the AWS CLI, and then go to the command such as AWS Athena with the help of the information that is available to view commands.
Users have to follow these steps to get started with Amazon Athena. So, first simply go to the AWS Management Console for Athena and then one must have to create your respective schema by taking up the DDL statements on the console or else by taking the help of creating the table wizard. After the completion of below steps, now the user can start a built-in query editor.
AWS Athena will support wide variety types of data formats such as TSV, CSV, Textfiles and JSON. Additionally, it also supports formats of open source columnar like apache parquet and apace ORC. Along with it, it also supports compressed data formats such as Zlib, LZO,GZIP and snappy. The users can also reduce costs and enhance the performance with the help of usage of columnar formats and compress.
AWS Athena will provide support to both simple data types like INTEGER, VARCHAR, DOUBLE and complex data types like MAPS, ARRAY and STRUCT.
In this process, the users can quickly access the data despite having a set-up or else managing any data warehouses and servers AWS Athena is serverless. In this, you have to just view your data in AWS S3, querying using the built-in query editor and also giving a perfect definition to the schema. It also allows the users to tap necessary data in S3 despite of having any set up of a complex process for loading data, transformation and extraction of data.
Users have to pay only for the queries that you will run in AWS S3 only and pay for the data that is scanned. You can even save up to 30% to 90% on each query and can enhance the performance by partitioning, compressing and conversion of the data into columnar formats. There will be no additional charges taken beyond the AWS S3.
Amazon Athena will be using a Presto with ANSI SQL support and will also work with different data formats such as JSON, ORC, CSV, Parquet and Avro. It performs an quick and ad-hoc querying and will also able to handle tough analysis phases such as window functions, large joins and even arrays. It is always available highly and mostly uses Amazon S3 as its underlying data stores, durable and data is highly available. It can also handle multiple devices in each facility.

It is highly interactive and performs very fast including the large data sets. It also delivers the unique and interactive query performance and will also allow executing the multiple commands in a parallel way to deliver high-end results.
AWS Athena is considered as the highly available and will be executing the queries using various resources of the computer across plenty of facilities and also routing queries in an automatic way. Mostly Athena will use Amazon S3 as it is highly available and with also durable infrastructure for storing a massive amount of data with ease and industry-centric approaches. The data in the platform can store various facilities and plenty of devices in each and every facility.
