Configure the processor for your data source
Learn how you can configure the ConsumeKafkaRecord_2_0 data source processor for your S3 ingest data flow. You can set up a data flow to move data to Amazon S3 from many different locations. This example assumes that you are streaming data from Kafka and shows you the configuration for the relevant data source processor.
-
Launch the Configure Processor window, by right clicking the
ConsumeKafkaRecord_2_0 processor and selecting
Configure.This gives you a configuration dialog with the following tabs: Settings, Scheduling, Properties, Comments.
- Configure the processor according to the behavior you expect in your data flow.
- When you have finished configuring the options you need, save the changes by
clicking the Apply button.
Make sure that you set all required properties, as you cannot start the processor until all mandatory properties have been configured.
In this example data flow, the data source is Kafka. You can create the modified Kafka broker URLs using the broker hostnames and adding port :9093 to the end of each FQDN. You can find the hostnames on the Streams Messaging cluster overview page when selecting the Hardware tab.The following table includes a description and example values for the properties required to configure the example ingest data flow. For a complete list of ConsumeKafkaRecord_2_0 properties, see the Apache Nifi Documentation.
