19 | Message Queuing: How to reduce the latency of messages in a message queuing system?
After studying the previous two lessons, I believe you already have an understanding of how to use message queues to deal with peak traffic during flash sales in vertical e-commerce projects. Of course, you should also know what to do to ensure that messages are not lost and try to avoid the impact of message […]

How to achieve low-latency RTSP or RTMP playback on VR headsets
Technical background VR (virtual reality technology) brings us an immersive visual experience and is widely used in urban planning, education and training, industrial simulation, real estate, water conservancy and electricity, interior design, culture and tourism, military and many other fields. It is commonly used in industries for example: Education industry: VR headsets can be used […]
How to quickly optimize CnosDB database performance and latency: use Jaeger distributed tracking system
In a formal production environment, the performance and latency of the database are crucial to ensure the stable and efficient operation of the system. Especially when interacting with the CnosDB database, it becomes even more important to have a deeper understanding of its behavior. At this time, the Jaeger distributed tracking system played a huge […]
Real-time distributed low-latency OLAP database Apache Pinot exploration practice
Pinot can ingest data directly from streaming data sources such as Apache Kafka and Amazon Kinesis, enabling instant queries based on real-time events. Data can also be ingested from batch data sources such as Hadoop HDFS, Amazon S3, Azure ADLS, and Google Cloud Storage. The core uses columnar storage, based on intelligent indexing and pre-aggregation […]

Java Virtual Machine – Low Latency Garbage Collector & Memory Allocation
3.6 Low Latency Garbage Collector Measure the three most important metrics of a garbage collector: memory footprint, throughput, and latency. With the expansion of memory, the requirements for latency will become higher and higher All collectors before CMS and G1, all steps of their work will produce a Stop The World-style pause. However, CMS and […]
Using Nginx in Kubernetes to Improve Reliability and Latency of Third-Party Services
This article discusses how to improve the performance and stability of third-party service access by configuring Nginx cache in Kubernetes. This method is implemented based on Nginx. The advantage is that access to cached third-party services can be realized without code development, but it also lacks some customized extensions. Cache write operations are not supported, […]
