Configure the processor for merging records

Learn how you can configure the MergeRecord processor for your ADLS ingest data flow. You can use it to merge together multiple record-oriented flow files into a large flow file that contains all records of your Kafka data input.

Launch the Configure Processor window, by right clicking the MergeRecord 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 Apply.

Make sure that you set all required properties, as you cannot start the processor until all mandatory properties have been configured.

In this example the following settings and properties are used:

Table 1. MergeRecord processor scheduling
Scheduling	Description	Example value for ingest data flow
Automatically Terminate Relationships		original

Table 2. MergeRecord processor properties
Property	Description	Example value for ingest data flow
RecordReader	Specify the Controller Service to use for reading incoming data.	CSVReader
RecordWriter	Specify the Controller Service to use for writing out the records.	CSVRecordSetWriter
Merge Strategy	Specify the algorithm used to merge records. The Bin-Packing Algorithm generates a FlowFile populated by arbitrarily chosen FlowFiles.	Bin-Packing Algorithm
Minimum Number of Records	Specify the minimum number of records to include in a bin.	900
Maximum Number of Records	Specify the maximum number of Records to include in a bin.	1000

Configure the processor for your data target.
