Question

How can I get number of partitions for any kafka topic from the code. I have researched many links but none seem to work.

Answer 1

//create the kafka producer
def getKafkaProducer: KafkaProducer[String, String] = {
val kafkaProps: Properties = new Properties()
kafkaProps.put("bootstrap.servers", "localhost:9092")
kafkaProps.put("key.serializer",
"org.apache.kafka.common.serialization.StringSerializer")
kafkaProps.put("value.serializer", 
"org.apache.kafka.common.serialization.StringSerializer")

new KafkaProducer[String, String](kafkaProps)
}
val kafkaProducer = getKafkaProducer
val noOfPartition = kafkaProducer.partitionsFor("TopicName") 
println(noOfPartition) //it will print the number of partiton for the given 
//topic
