When you set up a query as an aggregation task, it will give you great performance when you use it to feed widgets in an Activeboard, and also Devo applications. This is because an aggregation task creates a background task that continually updates and aggregates the query's values. This way new data is more quickly reflected in the widget the aggregation task is feeding. There is a yellow fast forward icon on widgets that can be optimized using aggregation tasks.

Using aggregation tasks (former data sources) in Activeboards Keep in mind that in Activeboards, aggregation tasks generated from a widget's source query are automatically used to optimize the widget performance, so you don't need to do anything more afterwards. Learn more about Activeboard widgets and how they work in Using widgets. |

Not with lookups To use aggregation tasks effectively, you must not create them using queries with lookups, otherwise, they might not work as expected. This is so because of technical reasons related to the interaction between the components behind them. |
