AMAZON ATHENA VS REDSHIFT WINDOWS

This allows Athena to run quick ad-hoc analysis as well as more complex requests including nested queries, large joins, windows functions, and arrays. It also supports a wide range of data formats including Avro, Parquet, CSV, JSON, and ORC. Benefits of Amazon AthenaĪthena uses Presto, an SQL query engine that was designed to run interactive analytic queries against data sources of all sizes. To reduce the cost, Amazon advises users to use compressed data files, have data in columnar formats, and routinely delete old result sets. How much does Amazon Athena cost?Īmazon Athena pricing is $5 to scan Terabyte data from S3, surrounded by the closest megabyte having a minimum of 10 MB per query. You only need to point to your data in S3, configure the schema, and start the query. Thus, it simplifies the process – you run the query from an easy-to-use web console. Instead, with Athena, your query can run without using ETL. The difference here is that you’re now using cloud computing services instead of a search engine.Īmazon Athena does not require setup or configuration, which is typically the case with a local data store and involves an ETL (Extract, Transform, Load) preparing data in a database for a query by isolating the dataset. A query is similar to a Google search in that you can create the parameters for the SQL query that you need to perform. You might know the data is out there, but sometimes it’s hard to find the data sets that you actually need.

One way to think about Athena? It’s somehow similar to a Google search. Athena uses a distributed SQL engine, Presto in order to run queries, Apache Hive to create and alter tables and partitions.

How does Amazon Athena work?Īmazon Athena works directly with S3 data. Athena scales automatically running queries in parallel, therefore results are fast, even with large datasets or complex queries. It does not store any personal data.Athena is serverless, so there is no infrastructure to set up or manage.

See how AtScale’s Intelligent Data Virtualization platform works in the new cloud analytics stack for the Amazon cloud (3 minute video): By leveraging tools like Amazon Redshift Spectrum and Amazon Athena, you can provide your business users and data scientists access to data anywhere, at any grain, with the same simple interface. With a virtualization layer like AtScale, you can have your cake and eat it too. S3) and only load what’s needed into the data warehouse. Often, enterprises leave the raw data in the data lake (i.e. Later, the data may be cleansed, augmented and loaded into a cloud data warehouse like Amazon Redshift or Snowflake for running analytics at scale. In today’s cloud-y world, just about all data starts out in a data lake, or data file system, like Amazon S3. In this blog, I will demonstrate a new cloud analytics stack in action that makes use of the data lake and the data warehouse by leveraging AtScale’s Intelligent Data Virtualization platform. Cloud data lakes like Amazon S3 and tools like Redshift Spectrum and Amazon Athena allow you to query your data using SQL, without the need for a traditional data warehouse. It’s no longer necessary to pipe all your data into a data warehouse in order to analyze it. Hadoop pioneered the concept of a data lake but the cloud really perfected it.
