- Snowflake uses a proprietary data storage format and you can't access data directly (even though it sits on S3). For example when using Snowflake-Spark connector, there is a lot of copying of data going on: S3 -> Snowflake -> S3 -> Spark cluster, instead of just S3 -> Spark cluster. The 2018 benchmark compares price, performance, and differentiated features for the most popular cloud data warehouses—Azure, BigQuery, Presto, Redshift, and Snowflake. This is a unique identifier within the community and often matches the first email you registered in the community.

When choosing a database schema for a data warehouse, snowflake and star schemas tend to be popular choices. This comparison discusses suitability of star vs. snowflake schemas in different scenarios and their characteristics.

Snowflake is great when you need to store large amounts of data while retaining the ability to query that data quickly. It is very reliable and allows for auto-scaling on large queries meaning that you're only paying for the power you actually use. It's taken queries that took 20+ minutes to run on redshift down to 2 minutes on Snowflake. Snowflake’s unique architecture empowers data analysts, data engineers, data scientists and data application developers to work on any data without the performance, concurrency or scale limitations of other solutions. Snowflake is a single, near-zero maintenance platform delivered as-a-service. When evaluating a query engine, it is important to consider holistically across a number of dimensions, including the momentum, vendor support, current feature set, and architecture for future evolution. Presto and Athena support reading from external tables using a manifest file, which is a text file containing the list of data files to read for querying a table.When an external table is defined in the Hive metastore using manifest files, Presto and Athena can use the list of files in the manifest rather than finding the files by directory listing. When evaluating a query engine, it is important to consider holistically across a number of dimensions, including the momentum, vendor support, current feature set, and architecture for future evolution. This is a unique identifier within the community and often matches the first email you registered in the community.
