Aggregations are a powerful tool to gain insights into your data, but how do they actually work? In this talk, we will explore:

• * how aggregations are executed 'under the hood'
• * what users should be aware of when running aggregations
• * the limitations of aggregations
• * some ways to tweak their execution for both performance and accuracy

Attendees will leave this presentation with a rich understanding of how aggregations can make their lives better and their data even more useful.
