Cassandra handles concurrent write conflicts by using atomic operations and eventual consistency. When multiple clients try to write to the same data simultaneously, Cassandra employs the Last Write Wins (LWW) approach to determine the final write result by comparing timestamps of each write operation and selecting the one with the latest timestamp.<\/p>\n

In Cassandra, timestamps are unique identifiers used to compare the order of write operations. When multiple clients write the same data simultaneously, Cassandra uses the timestamps passed by the clients to determine which write operation should be accepted as the final result. If two write operations have the same timestamp, Cassandra uses the node’s UUID as the basis for conflict resolution.<\/p>\n

When dealing with concurrent write conflicts, Cassandra will keep a record of the history of all write operations and provide all historical versions of the data during subsequent read operations. This ensures the integrity and consistency of the data while preserving information about all write operations.<\/p>\n","protected":false},"excerpt":{"rendered":"
