The Pulsar community hit two major milestones: Pulsar welcomed its 400th contributor last month and Pulsar surpassed Kafka in the number of monthly active contributors. We want to thank everyone in the Pulsar community who contributed.

Community Growth

Community growth and engagement are at the core of every open-source project. The number of contributors (400) signals project adoption and advancement while the number of monthly active contributors indicates the vibrancy of the Pulsar community.

1. 400 Contributors and 2x Growth

The 400th contributor milestone shows the size of the community and the fact that the number of contributors has more than doubled in the past two years shows the trajectory of the project. The charts below provide an overview of key Pulsar milestones.

Apache Pulsar Surpasses Apache Kafka

Pulsar recently surpassed Kafka in the number of Monthly Active Contributors. This is significant because Kafka is a large and widely adopted project often considered a lot bigger than Pulsar. As this graph demonstrates, the adoption of Pulsar and engagement in the project has skyrocketed over the last few years and it now has more monthly engagement than Kafka.

3. Apache Pulsar Github Stars

Github stars are another key metric for open source projects. The chart below shows the accelerating growth for Apache Pulsar.

Ecosystem Development

Since the Pulsar project gained its 300th contributor last August, the Pulsar ecosystem has seen a number of updates. Below we look at a few key product launches.

1. Function Mesh - Simplifying Complex Streaming Jobs in the Cloud

Function Mesh is an ideal tool for those who are seeking cloud-native serverless streaming solutions. It is a Kubernetes operator that enables users to run Pulsar Functions and connectors natively on Kubernetes, unlocking the full power of Kubernetes’ application deployment, scaling, and management. Function Mesh is also a serverless framework to orchestrate multiple Pulsar Functions and I/O connectors for complex streaming jobs in a simple way.

2. AWS SQS Connector - Seamless Integration between SQS and Pulsar

The SQS connector enables users to integrate Pulsar with SQS easily, quickly, and securely. Organizations can move data in and out of Pulsar without writing a single line of code. This connector can run jobs on a single node or for an entire organization, which allows users to build reactive data pipelines to serve their business and operational needs in real-time.

3. Cloud Storage Sink Connector - Streaming Data from Pulsar to Cloud Objects

Depending on your environment, the Cloud Storage sink connector can export data by guaranteeing exactly-once delivery semantics to its consumers. It provides applications that export data from Pulsar all the benefits of Pulsar IO, such as fault tolerance, parallelism, elasticity, load balancing, on-demand updates, and much more.

4. MQTT-on-Pulsar (MoP) - Bringing Naitve MQTT Protocol Support to Pulsar

By adding the MoP protocol handler in existing Pulsar clusters, users can migrate their existing MQTT applications and services to Pulsar without modifying the code. This enables MQTT applications to leverage Pulsar’s infinite event stream retention with Apache BookKeeper and tiered storage.
