All About Aggregations
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.
