Aggregators collect data from source services or other aggregators and publish the data to target services or other aggregators. Aggregators read data in events. An event consists of one or more complete records. A record consists of data and can contain a delimiter. Specify the number of events that an aggregator can read when you configure it.
You can use aggregators in the following scenarios:
- To handle many-to-one and one-to many data flows effectively.
- To aggregate data from multiple source services and write the data to target services.
- To aggregate data from one or more aggregators and write the data to one or more aggregators through a firewall.
- To aggregate data from source services spread across geographies.
You can add one or more aggregators to a data flow. You can add transformations to aggregators. You can also view related statistics.
