Apache Pulsar VS ApacheKafka

Ingest real-time data from Kafka, Pulsar, or CDC sources like Postgresand MySQL, with built-in support for Debezium.

Apache Pulsar: Pulsar is a distributed messaging platform developed under the Apache Foundation. Its notable features include extremely low latency, support for multi-tenancy, geo-replication across regions, and tiered storage capabilities.

From Apache, there's Pulsar, a distributed pub-sub messaging platform with a flexible messaging model, and an intuitive client API. The latest version brings enhanced Key_Shared subscription implementation, secure Docker runtime based on Alpine Linux and Java 21, rate limiting, enhanced client compatibility, and more. Check out the release notes to read more about all the changes since the last release.

Apache Pulsar is an open-source distributed messaging platform originally developed by Yahoo! It provides a highly scalable solution for messaging and stream processing with robust durability and fault tolerance.

Stream-processing platforms such as Apache Kafka, Apache Pulsar, or Redpanda are specifically engineered to foster event-driven communication in a distributed system and they can be a great choice for developing loosely coupled applications. Stream processing platforms analyze data in motion, offering near-zero latency advantages. For example, consider an alert system for monitoring factory equipment. If a machine's temperature exceeds a certain threshold, a streaming platform can instantly trigger an alert and engineers do timely maintenance.

Edit: Here's a good example of what I'm looking for: https://github.com/apache/pulsar. It is a full application that happens to be deployed (or deployable) with Terraform, and the configuration files are available.

In recent years, it has become apparent that almost no production system is complete without real-time data. This can also be observed through the rise of streaming platforms such as Apache Kafka, Apache Pulsar, Redpanda, and RabbitMQ.

It's colored black on the refreshed Apache Pulsar site. https://pulsar.apache.org/

10. Apache Kafka (apache/kafka) – Distributed Streaming Platform

Alternatives to: Redis (Queue, Pub/Sub), ZeroMQ, RabbitMQ, Apache Kafka, Amazon Simple Queue Service, Google Cloud Pub/Sub

Kafka: Our trusty message bus. Events land here first.

For those interested in a deeper dive into Apache Kafka’s multifaceted world, further details can be found on the official Kafka website and the Apache Kafka GitHub repository. Additionally, exploring innovative funding models via resources like tokenizing open source licenses provides insight into the future of open source software sustainability.

Apache Kafka: Official Site

Real-time pipelines might need RisingWave or Apache Kafka.

Although Twitter internally uses Apache Kafka (Apache Kafka), they also utilize Google’s Cloud Pub/Sub service. However, Twitter has the flexibility to replace Cloud Pub/Sub with alternative open-source systems, such as:
