Final answer:
In multi-site clusters, attributes such as site information, replication factors, and search affinity are added to the Cluster Master to manage distributed nodes across multiple locations, ensuring data integrity and efficient content retrieval.
Step-by-step explanation:
When moving to multi-site clusters, several attributes are added to the Cluster Master to handle the complexities of a distributed environment. Multi-site clustering is utilized to achieve high availability and disaster recovery by distributing the cluster's nodes across multiple physical locations. In this setting, attributes such as site information, replication factors, and search affinity are introduced to the configuration. Site-related attributes define the geographical distribution of nodes, ensuring that the cluster is aware of the physical location of each peer and can manage data accordingly. The replication factor is adjusted to maintain multiple copies of data across different sites, allowing for continued operation if one site goes down. Search affinity settings are used to optimize query performance by attempting to execute search queries at the same site where the data resides to reduce cross-site bandwidth usage. Overall, these attributes work together to maintain data integrity and availability in the event of site outages and ensure efficient content loaded and retrieval across diverse geographical locations.
