  • Answer to How many topics (queues) can be created in Apache Kafka? – Quora

    Good to know:

    ‘As far as I understand (this was true as of 2013, when I last looked into this issue) there’s at least one Apache ZooKeeper znode per topic in Kafka. While there is no hard limitation in Kafka itself (Kafka is linearly scalable), it does mean that the maximum number of znodes comfortable supported by ZooKeeper (on the order of about ten thousand) is the upper limit of Kafka’s scalability as far as the number of topics goes.’
