In recent years, with the popularization of new technologies such as distributed system architecture, microservices concepts, and PaaS service components in the financial industry, traditional monolithic business system architectures based on mainframes and storage are rapidly evolving towards distributed system architectures based on cloud foundations (referred to as new system architecture). The new system architecture … Read more
When Data Needs to Cross Oceans: Achieving Geographical Synchronization with Multi-Region Replicator You may have encountered scenarios where an order submitted by a user in New York cannot be queried in Tokyo, a database failure in Frankfurt causes service interruptions across Europe, or a user in Sydney complains that the shopping cart loads slower than … Read more
Fjall – A Safe Rust KV Storage Engine Fjall is an embeddable, LSM-based, forbid-unsafe Rust key-value storage engine. Its goal is to be a reliable and predictable yet high-performance general-purpose KV storage engine suitable for small datasets, especially those larger than memory size. I have just released version 1.0, which stabilizes its data format for … Read more
Wireless Sensor Networks (WSN) are self-organizing network systems composed of a large number of low-power, multifunctional sensor nodes that communicate wirelessly, used for sensing, collecting, transmitting, and processing environmental information.It is widely used in various fields such as military reconnaissance, environmental monitoring, industrial control, smart homes, and healthcare. The development history of WSN is a … Read more
