Multi-master replication, introduced in the late 1980s, is a method in database management where each node or server in a database system can both send and receive updates. In this architecture, any changes made to one node are replicated to all other nodes, ensuring that every node maintains an up-to-date copy of the database. This approach provides high availability and redundancy, as the system can continue to operate even if one node fails. However, it also presents challenges in managing conflict resolution and ensuring consistency across all nodes, especially in systems with a large number of nodes or those that handle a high volume of transactions.
