ZeroMQ vs Apache Pulsar: What are the differences?

What is ZeroMQ? Fast, lightweight messaging library that allows you to design complex communication system without much effort. The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.

What is Apache Pulsar? Distributed solution providing messaging and queuing for streaming data. Apache Pulsar is a distributed messaging solution developed and released to open source at Yahoo. Pulsar supports both pub-sub messaging and queuing in a platform designed for performance, scalability, and ease of development and operation.

ZeroMQ and Apache Pulsar can be primarily classified as "Message Queue" tools.

Some of the features offered by ZeroMQ are:

  • Connect your code in any language, on any platform.
  • Carries messages across inproc, IPC, TCP, TPIC, multicast.
  • Smart patterns like pub-sub, push-pull, and router-dealer.

On the other hand, Apache Pulsar provides the following key features:

  • Unified model supporting pub-sub messaging and queuing
  • Easy scalability to millions of topics
  • Native multi-datacenter replication

"Fast" is the top reason why over 19 developers like ZeroMQ, while over 4 developers mention "Simple" as the leading cause for choosing Apache Pulsar.

ZeroMQ and Apache Pulsar are both open source tools. ZeroMQ with 6.25K GitHub stars and 1.8K forks on GitHub appears to be more popular than Apache Pulsar with 6.24K GitHub stars and 1.51K GitHub forks.

According to the StackShare community, ZeroMQ has a broader approval, being mentioned in 52 company stacks & 131 developers stacks; compared to Apache Pulsar, which is listed in 3 company stacks and 43 developer stacks.

    What are some alternatives to Apache Pulsar and ZeroMQ?
    Kafka
    Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
    RabbitMQ
    RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
    NATS
    Unlike traditional enterprise messaging systems, NATS has an always-on dial tone that does whatever it takes to remain available. This forms a great base for building modern, reliable, and scalable cloud and distributed systems.
    Amazon SQS
    Transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. With SQS, you can offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use.
    Celery
    Celery is an asynchronous task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well.
