strømmirror
Strømmirror is a concept in distributed systems that describes a mechanism for maintaining real-time mirrors of a primary data stream across multiple geographically dispersed nodes. The goal is to enable low-latency access to up-to-date information while preserving the order and integrity of the original stream. The term blends "strøm," meaning stream in several Nordic languages, with "mirror."
A strømmirror setup typically comprises a source stream producer, a streaming transport layer, and multiple follower
Applications include real-time analytics, content delivery and edge caching, database replication, and disaster recovery. In cloud-native
Challenges include network latency and jitter, bandwidth costs, fault tolerance, cursor management, time synchronization, and security
