Possible disadvantages of Apache Pulsar

  • Resource Intensive
    Operating a Pulsar cluster can be resource-intensive, requiring significant computational resources, especially when dealing with high-throughput scenarios.
  • Less Community Support
    As a relatively newer project compared to some competitors, Pulsar has a smaller community, which could impact the availability of support and third-party expertise.
  • Learning Curve
    Pulsar's architecture and features, though powerful, come with a steep learning curve, demanding considerable time and effort to master for effective use.
