Powering Federated Learning at Tencent with Apache Pulsar

Tencent Angel PowerFL is a distributed federated learning platform which can support trillions of concurrent training. Angel PowerFL has been widely used in Tencent Financial Cloud, Advertising Joint Modeling, and other businesses. The platform requires a stable and reliable messaging system with guaranteed high performance and data privacy. After investigating different solutions and comparing several messaging queues, Angel PowerFL adopted Apache Pulsar as the data synchronization solution in Federated Learning (FL).

In this blog, the Tencent Angel PowerFL team shares how they built federated communication based on Pulsar, the challenges they encountered with Pulsar, and how they solved those problems and contributed to the Pulsar community. Tencent’s use of Pulsar in production has demonstrated it provides the stability, reliability, and scalability that the machine learning platform requires.
