Add a pre-aggregation

In this step, we'll add a pre-aggregation to optimize the performance of a specific query. Pre-aggregations are a caching technique that massively reduces query time from seconds to milliseconds. They are extremely useful for speeding up queries that are run frequently.

From the Build tab, execute a query:

<Frame> </Frame>

Just above the results, click on Query was not accelerated with pre-aggregation to bring up the pre-aggregation suggestion:

<Frame> </Frame>

A pre-aggregation will be automatically suggested for the query; click Add to the Data Model and then retry the query in the Playground. This time, the query should be accelerated with a pre-aggregation:

<Frame> </Frame>

And with that, we conclude our Getting Started with Cube guide. If you'd like to learn more about Cube, check out this page.
