At least we could not find any mention of such a feature.The other type of caching is result caching. Extrapolated to 1 TB that gives us 827s or ~14 minutes. Compare this to other data warehouse platforms. There aren’t too many knobs or parameters to set or tune.
Athena is a blackbox when it comes to scaling and concurrency. You don’t have to worry about ORC or Parquet, or compression. Athena is mainly supported by AWS tools such as Quicksight etc.Both platforms support JSON. Amazon then adopted the model and released AWS Athena in early 2017. Uli has architected and delivered data warehouses in Europe, North America, and South East Asia. With Snowflake you have to perform considerably less ETL work.
In this blog post we look at the commonalities and differences between the Snowflake cloud data warehouse and the AWS Athena query service. As per Snowflake philosophy everything is taken care off for you.
At the same time you get superior functionality and performance for a similar or even lower price tag.Have you had any experience with AWS Athena, PrestoDB, or Snowflake? If your company is already working with AWS, then Redshift might seem like the natural choice (and with good reason). We could not find any way to scale a query by throwing hardware/money at the problem. Quite amazing. Snowflake is only available in the cloud on AWS and Azure.Both Snowflake and Athena come with SDKs. For Snowflake this happens automatically. But it will not get you very far in terms of automating the whole conversion process from XML/JSON to relational data.Athena is built on top of Presto DB and could in theory be installed in your own data centre. This is quite similar to the BigQuery model where the user does not have any control over scaling individual queries.Snowflake has unlimited concurrency. For Athena it is a manual process. There are no knobs to tune or administer. It shouldn’t come as a surprise then that Athena does not have any of the mature features you would expect from a relational data warehouse platform such as ACID, transactions etc. The use case is very limited.
It is all done for you. It is based on Presto DB, a SQL engine with its roots in the Hadoop world.Storage on Athena is immutable, which means that you can’t update, upsert, or delete individual records.
This pricing model for data analysis was pioneered by Google (BigQuery) and Snowflake. Both are fully automated on Snowflake.Both Snowflake and Athena offer the usual security features such as encryption, authentication and authorisation.Snowflake has a security feature that allows you to secure data at the column and row level.With Snowflake you can set up a multi-tenant environment and only expose certain data sets to some of your users. The query executed in 316s. You don’t need any DBAs either.
Upgrades, backups etc. What is Snowflake? you could spin up a virtual warehouse for a demanding ETL job or another one for your power users. Both services follow a pay as you go model. The cost stays constant.
before you are ready to rock.
Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Pricing starts at $2 per hour (minimum of 1 minute billed; by the second thereafter. With Athena you pay for storage and the amount of data that is scanned during a query. Combined with AWS Glue, Athena is even able to auto-generate schemas for you. However, with BigQuery you are charged for the raw/uncompressed data whereas for Athena you pay for the data (either compressed or in raw format depending on your scenario).
We discuss the limitations of this further down in the post.Snowflake is a proper relational data warehouse platform and supports transactions, different isolation levels, ACID, read consistency and multi version concurrency control (MVCC).
You can request an increase of this limit by contacting AWS support.Snowflake comes with a mature cost based optimizer (CBO).
We use Cookies to improve your browsing experience on our Site. Partitioning and clustering (similar in concept is bucketing on Athena) are manual processes on Athena.
You can achieve something similar on Snowflake using Fivetran and similar tools.
And even then you better be careful with your queries. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. We see Snowflake slightly ahead, e.g. Athena bills only for run queries while Snowflake puts servers in sleep mode after a few minutes of …
AWS Athena is built on top of open source technology Presto DB.
The result of CBO planning can be examined using You don’t need to gather statistics in Athena either. Yes, in Snowflake you have to load your data and create a schema, but the platform takes care of everything else for you.

However, as I have outlined in my article on Both engines offer a mature set of SQL features.
Snowflake has its roots in the world of relational databases.Athena is positioned as a query service for running queries against data that already sits on S3. You get stuff done 2x, 4x, 8x, 16x etc. This is very different to a traditional MPP database such as Redshift, Teradata, Vertica etc.
