I have recently come across a video on YouTube similar to this. Sharing it here might help - CTTO

It's intentionally obfuscated through the Appian-based abstraction layer (the data store, at least for the older data types), particularly so that they can shift things around in the back-end on a progressive basis to tweak efficiency without breaking the way things work on the Designer front-end. That's all a long way of saying, we don't "officially" have any way of directly knowing what the exact SQL is that eventually gets passed to the DB via the Appian query, but it's reasonably safe to assume that by now they've probably fine-tuned it to be reasonably close to the most efficient thing possible.

Appian translates the expression into a corresponding SQL query and sends it to the database.

When these aggregation functions are used, Appian generates SQL queries that include GROUP BY clauses, and these queries are sent to the database engine for execution. Appian does not bring all the data into its memory and then perform grouping on it.

Hello ougdp2003,

Your query aggregation is used as an SQL statement for execution.

Aggregation and filtering happen on the Database level.

Aggregations are translated into SQL statements and sent to the DB for execution.
