It divides data into multiple segments (also known as fragments) according to certain rules and stores these segments on different servers or storage nodes. The goal of fragmentation is to achieve horizontal scalability, load balancing, and improve query efficiency and data availability. In distributed systems, fragmentation can effectively reduce the impact of single-point failures, improving system stability and reliability. Common fragmentation techniques are applied in fields such as distributed databases, caching, and message queues. For example, Redis clusters and Kafka message queues use fragmentation technology to achieve distributed storage and processing  of data."}]}],"pr":"47a3d7c4d51987eaab733f2a72e8e93f54e6c06f2b61eca9be27632ded98adbc"}
