PublishKafka sends the entire flow file to Kafka as a single message. PublishKafkaRecord splits each "record" (e.g. row) in the flow file and sends each record as a message.

So if I have used JSON transformations on my data and each time 100 flow file are generated so I guess both will be equivalent ...

If your files contain one record each, then yes, these NiFi processors will be equivalent.
