How to assign all the partitions of a topic to consumer ?

[Kamal C]

Hi,

    I'm using the new consumer in assign mode. I would like to assign all
the partitions of a topic to the consumer.

For that, I need to know the number of partitions available in the topic.

*consumer.assign(List<TopicPartitions> partitions);*

How to programmatically get the number of partitions in a topic?
