After nearly 10 years of development of Tencent Game big data, the daily data transmission volume can reach 1.7 trillion. As the key component of the big data platform, the MQ system is critical to provide real-time service operational quality assurance, which requires the support of various applications such as real-time game operational service, real-time index data analysis, and real-time personalized recommendation.
Softtech
Softtech built an event-based consent management system with an average throughput of 500 Million messages per day on Pulsar.
Overstock
By combining Apache Pulsar Functions with Apache Ignite, we achieve low latency lookup performance for real-time enrichment of data, which is useful for search and other real-time use cases.
Flipkart
At Flipkart, there are multiple use-cases for high throughput messaging like streaming/batch pipelines, ordered processing, auditing, etc. Pulsar offers different kinds of isolation mechanisms: cluster peering, isolation groups, produce/dispatch quotas, etc. We identified that offering topic-as-a-service can take away operational complexity for these teams and help us enforce stricter SLAs around uptime and geo-replication. Therefore we approached building a scalable and multi-tenant platform with Pulsar as the choice of backend.
GeTui
We adopted Pulsar for the new priority-based push notification solution.
Qraft
We choose Pulsar for its ability to manage distributed transactions within a microservice architecture and its feature flexibility. Pulsar now plays an essential part in helping our AI-powered order execution system to find the optimal strategy in real time.
BIGO
The messaging team at BIGO found themselves overwhelmed by the massive amounts of data when using Kafka. They then started to learn Apache Pulsar and ran some tests with it, after which they believed Pulsar could be a solution to their challenges. They use Pulsar as a key component in their real-time messaging architecture, which has helped them reduce the hardware cost by 50%.

Cisco
Cisco IoT Control Center is among the world's largest IoT platforms, with numerous data centers spread across continents, hosting thousands of applications for the management of hundreds of millions of IoT devices, including connected cars and wireless phones. Cisco underwent a two-year process of transforming their platform into a cloud-native GitOps platform, where Pulsar replaced legacy message queue services and is deployed across multiple Kubernetes clusters.
Keytop
Keytop redesigned its messaging system by using Apache Pulsar as the backbone of its architecture. Its geo-replication feature helps Keytop securely store mission-critical data across multiple data centers.

Discord
Discord encountered the task of enhancing its live streaming machine learning platform to tackle safety and personalization concerns, like restricting spam access or safeguarding Discord users' accounts from potential breaches. The current setup was designed for heuristics, not for machine learning. The necessity for a reliable, scalable, and real-time solution prompted them to consider incorporating Apache Flink, Pulsar, and Iceberg.
Nutanix
Apache Pulsar offers server as well as client side support for the structured streaming. We have been using Pulsar for asynchronous communication among microservices in our Nutanix Beam app for over an year in production.
Clever Cloud
We're using Apache Pulsar as the foundation for our cloud backbone and developed KoP (Kafka on Pulsar).
Splunk
Pulsar guarantees data consistency and durability while maintaining strict SLAs for throughput and latency. Furthermore, Apache Pulsar integrates Pulsar Functions, a lambda style framework to write serverless functions to natively process data immediately upon arrival. This serverless stream processing approach is ideal for lightweight processing tasks like filtering, data routing and transformations.
TurtleQueue
Apache Pulsar (upon which TurtleQueue is built) builds on top of the same foundation and improves on it. It exposes a cursor that advances to consume the next message. The cursor's position can be changed to something else, like the beginning of the queue.
Netdata
The heart of Netdata Cloud is Pulsar. Almost every message coming from and going to the open source agents passes through Pulsar. Pulsar's infinite number of topics has given us the flexibility we needed and in some cases, every single Netdata Agent has its own unique Pulsar topic.
Instructure
We researched, advocated, built, integrated, and established Apache Pulsar at Instructure in less than a year.
Yahoo!
We deployed our first Pulsar instance in Q2 2015. Pulsar use has rapidly grown since then, and as of today, Yahoo runs Pulsar at scale.
ProxyClick
It gives us consistency with the messages in the queue. It also allows us to replay messages, and it’s a very powerful tool for the distributed systems that like us.
Newland
Apache Pulsar has multi-layer and segment-centric architecture and supports geo-replication. We can query data with PulsarSQL, and create complex processing logic without deploying other systems with Pulsar Functions.
