Differing from our industry leading analytics engine, Direct Query generates SQL queries on the fly against the source and executes the query and compute at the database level. From big data to near real time use cases, Direct Query empowers users of any level to easily explore and analyze the most recent data right from the database, increasing the speed to insight and decision-making.
Direct Query complements our best-in-class analytics engine and extends the range of consumption techniques for analyzing data from cloud databases. The first connector rolling out for Direct Query will be for Snowflake with Databricks next on the roadmap and others planned, so stay tuned.

How does Direct Query work?
Direct Query can be activated at the database connection level. So, using Snowflake as the example, when building a new application and starting with a data connection, you will have the option to use Direct Query versus our analytics engine.
The user can then select certain components of the source database –in the Snowflake connector users will see the options for role, database, and schema. Authentication for Direct Query is governed at the database level so users will only have access to what is granted from the source database.
The user can then select a single view or multiple tables with the option of choosing the type of relationship between the data sets like full outer join or inner join.
Once the relation is designated, an import live statement is inserted into the script in the load editor on the back-end and the visualizations can begin being built on the front-end. Since this is a SQL pushdown tool, users will need to use the function library of the underlying database. As of this blog, we will support the major 5 aggregations of sum, avg, min, max, and count. Also, some simple forms of set analysis will be available for filtering within measures of charts.
After the charts and objects have been built, users can filter and interact with data in real time as Direct Query generates SQL on the fly and pushes the query and compute down to the source database. Keep in mind that every selection or filter within the app from a user, results in a query pushed down to the database and compute.
Direct Query will also feature a seamless transition into our analytics engine for advanced interactivity and the full suite of capabilities. Check out Part 2 ‘Building Hybrid Solutions’ from the videos below.
