Aggregators combine multiple bundles into a single operation. If you send in 10 bundles, out comes 1 single text bundle.
Compose a string will compose a string for each bundle, while still passing through the original number of bundles sent to it. If you send in 10 bundles, you use 10 “Compose a strings”, and 10 output bundles.
Aggregators
Every result (item/record) from iterator/list/search/match modules will output a bundle. This can result in multiple bundles, which then trigger multiple operations in future modules (one operation per bundle). To “combine” multiple bundles into a single variable, you’ll need to use an aggregator of some sort.
Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and can apply to many use-cases like building of JSON, CSV, HTML.
There are other types of aggregator modules, click the below links to find out more:
- Array aggregator
- Text aggregator
- Numeric aggregator
- Table aggregator
- JSON aggregator
- CSV aggregator
- Archive (ZIP) aggregator
- other app-specific aggregators
Hope this helps! Let me know if there are any further questions or issues.
