Description: Node replacement is the process of replacing a failed node with a new one in a distributed cluster. This process is crucial for maintaining data availability and integrity in distributed systems. In such clusters, each node is responsible for storing a portion of the data and participating in managing read and write operations. When a node fails, it can affect the cluster’s ability to handle requests, potentially leading to data loss or performance degradation. Node replacement involves adding a new node to the cluster, which is configured to take over the responsibilities of the failed node. This process includes data synchronization, where the new node is filled with the necessary information from other nodes in the cluster, ensuring that there are no service interruptions. Additionally, node replacement can be performed automatically or manually, depending on the cluster’s configuration and the management tools used. The ability to efficiently replace nodes is one of the features that make distributed systems a popular choice for applications requiring high availability and scalability, such as social networks, e-commerce, and data analytics platforms.
