Welcome to Tencent Cloud + community, get more Tencent mass technology practice dry goods oh ~

Cloud + Introduction: On April 22, The Tencent Cloud + Community technology salon Kafka Meetup shenzhen station hosted by Tencent Cloud and Kafka community and co-organized by Open Source China was held in Tencent Building. The whole event was full of goods, not only Kafka’s past life and outlook, but also in-depth analysis of Kafka’s technical architecture. At the same time, kafka-based application platform related development and operation and maintenance practice. The activity was extremely popular, with nearly 300 participants participating in the exchange. Many participants said that the quality of the activity was very high and the trip was worthwhile.

Design and implementation of Zhihu Kafka platform based on Kubernetes

The next speaker, Bai Yuqing, is the head of Zhihu Technology Center. He will bring “Design and Implementation of Kafka Platform Based on Kubernetes in Zhihu”, sharing the application of Kafka in Zhihu, why Kafka platform based on K8S, and how to make such a platform. Zhihu has applied Kafka in logging, data transmission and message queue services. Kafka has become an important component of Zhihu’s technology platform and has been running smoothly for two years, according to Bai Yuqing.

Tea to ask questions



Application of CKafka in face recognition PaaS

Back to the second half of sharing, the first is the application of CKafka in Face recognition PaaS brought by Chen Xinyu, the head of research and development of Deep Pupil Cloud data stream of Gling. Spirit deep pupil’s massive picture face recognition service using the optimized tencent cloud CKafka, used in business data import, cache, output, and monitor and log collection and so on each link, connecting the various data processing module, for real time human face feature extraction, comparison and analysis provides the security, is the core of image flow real-time face recognition platform. Chen Xinyu introduced the position and importance of Kafka in deep learning face recognition platform architecture from the application level, and introduced some applications and problems of Kafka ecological components such as Connect.
