Data Center Resilience
When a data center goes offline, the surviving data center typically does not replicate data to maintain the desired number of copies, as the outage is often temporary. Instead, the focus should be on adding more machines to enhance capacity rather than increasing replication counts. Cassandra employs mechanisms like read repair, hinted handoff, and anti-entropy repair to ensure data consistency without the need for costly rebuilds, providing a significant advantage over traditional relational databases.In this clip
