(I'm the author of the post.) I've worked with a large Postgres cluster before (~1PB of data) and have been experimenting with Snowflake recently. I would say there's two clear technical advantages of Snowflake over Redshift. First is there's no maintenance when using Snowflake. You just signup for a Snowflake account, upload a CSV, and you can start querying the data. This is in contrast to Redshift where you have to manually provision a cluster, resize it as you add more data, etc. The second is their pricing. Storing data in Snowflake costs the same as it would cost to store in S3. The tradeoff is you also have to pay based on how long your queries take. Depending on your workload this can result in a massive cost savings. If you access only small amounts of your data infrequently, it's like you're storing the data in S3 and you only have to pay a bit more when accessing the data. This is in contrast to Redshift where you have to pay for the full cost of the cluster regardless of whether you are actually querying the data or not. Snowflake also has a ton of quality of life improvements compared to Redshift. One really nice thing is you can change the amount of compute used for any individual query. For example, if you have one specific slow query, you can allocate 4x the compute for that one query, pay 4x as much while the query is running, and get the query to run 4x faster (ultimately costing you the same amount as if you used 1x the compute). One neat thing is there's ultimately only one "Snowflake instance" in each region. Everyone's tables are in the same instance, but you can only access the tables you have permission to access. This allows you to easily share data between different Snowflake accounts. You can store the data in one account and query it from another. So the core value proposition is really strong and it also has a bunch of extra features that are all pretty useful at the end of the day. This post focused on Snowflake solely from a business point of view. I'm considering writing another one that focuses on it from a technical point of view.
