Description

Receives Record-oriented data (i.e., data that can be read by the configured Record Reader) and evaluates the user provided script against each record in the incoming flow file. Each record is then grouped with other records sharing the same partition and a FlowFile is created for each groups of records. Two records shares the same partition if the evaluation of the script results the same return value for both. Those will be considered as part of the same partition.
