Have you tried renting a car lately? The rates are surprisingly high. And I have the data to prove it:
Each of these lines represents the average quoted price for car rentals in LA, Las Vegas, Miami, Chicago, and San Francisco — starting in 2019, and ending in record high prices right now.
The goal for this post is to build a function you could use within Snowflake to forecast time series. A great open source tool for this is Facebook Prophet, and we just need a way to use it within our Snowflake environment. This is easy, with Snowflake’s ability to run external functions — hence we only need to host an instance of Prophet and add the necessary plumbing to end up with a
prophetize(timeseries) function within Snowflake.
Let’s start with a demo, any time series in Snowflake will do: For example, the temperature around New York City in the Newark…
Let’s say your customers are superheroes, and you have a table that contains data about them. You know a lot about your customers, and they trust you to protect their identities and privacy — not only from third parties, but also from people in your company that need this data to do their job, but not all of this:

Eva Murray is a Tableau Zen master and a leader for #MakeOverMonday — and she just joined Snowflake! She loves data storytelling, and when she found thousands of datasets in the Snowflake Data Marketplace — she decided to take this challenge. We taped a call discussing her first 7 days of visualizations — and you can find it here:
Let’s check some of her visualizations and my thoughts:
Check TJ Murphy’s reaction when he discovered that Snowflake now has support for
“We have an e-commerce shop. We need to identify sessions that land into the website from an arbitrary referrer (Instagram, Facebook, etc), and that end up buying something. How many steps did it take for these users to buy something, and how many times they tried to pay before success?”
That’s not an easy question to answer with plain SQL. But
MATCH_RECOGNIZE finally gives us an elegant way to find answers to question like this one.
MATCH_RECOGNIZE we can simply define the steps we…
This is a map that shows the most popular type of restaurant for each state around the US, and the pattern is clear — states around the East love pizza, states around the West love Mexican food:
But there are some exceptions:
To build this map I used the Foursquare Places premium dataset, through the Snowflake Data Marketplace. You can find my queries below.
This dataset includes more than 96 million places from all over…
2021–03–11: Few countries have vaccinated more than 4% of their population. Gibraltar and Israel display outstanding numbers at almost 50%. They are followed by Seychelles (27%), Bermuda, Cayman Islands, Bahrain, USA, Serbia, Malta, Faeroe Islands, and Chile (6.64%).
What’s interesting about this query:
owid_vaccinationstable reports interesting statistics like # of daily vaccinations, % of population vaccinated, and the specific vaccines each country is using.

There are four questions that you could answer, each focusing on a different industry: financial services, healthcare, media & entertainment, and retail/CPG. For example, one of the questions is
