回复: 回复：Deciding number of partitions

["sgh6688@163.com" <sg...@163.com>]

well, it's complicated to decide the num of partitons, it's up on your application. I think 8-64 is a better practise for most application, such as 16/32 partitions with 2 or 3 replicas. 
generally,
the less the num of partitions you have , the less tps you will get,
the more the num of partitions you have, the more cpu/io/mem/fd...  it will occupies.  And too many partitons means too many files which means sequence writting will be broken to random writting and reading.

forgive my poor English~

Hi,
  Maybe you can use the command like: 
    kafka-topic.sh --create --topic <topic_name> --partitions <partition_number>  --replication-factor <replica_number> --zookeeper <zookeeperIP:Port>
  I hope it helps!
 
 
Regards!
Cathy
