For example, you might have an object that represents the delivery of an advertisement called AdEvent
. Let’s assume an AdEvent
has three relevant properties: accountName
, campaignName
, and adName
. In order to summarize by all three properties, set your groupBy
property as follows:
groupBy=accountName,campaignName,adName
This causes the summarizer to only consider two AdEvents
as matching if all three of the properties are the same. To summarize by campaigns instead (regardless of accounts or ads), set the groupBy
property to:
groupBy=campaignName
This causes the summarizer to consider two AdEvents
as matching if their campaignNames
are equal. You can have more than one summarizer listening for the same data items. So if you want to combine the last two summarization examples, configure two summarizers and have them both listen for the same data items.
