Hi Rakesh,
generally, you don’t worry too much about the partitions, they’re mostly for processing parallelism. Instead, you use the topics themselves to route data where you want it to go.
but in case you really want a specific Consumer to handle a specific partition, you can use ‘assign’ and give to the TopicPartition you want. See https://kafka.apache.org/22/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html#assign-java.util.Collection-
I hope this helps!

But then again one can manually assign partitions if required.

Hey Rajesh,
Consumer has a self managed assign mode to read from the topic you choose.
