Multi-master replication can also be contrasted with failover clustering where passive replica servers are replicating the master data in order to prepare for takeover in the event that the master stops functioning. The master is the only server active for client interaction. Often, communication and replication in Multi-master systems are ...
MySQL Cluster is designed around a distributed, multi-master ACID compliant architecture with no single point of failure.MySQL Cluster uses automatic sharding (partitioning) to scale out read and write operations on commodity hardware and can be accessed via SQL and Non-SQL (NoSQL) APIs.
SymmetricDS is open source software for database and file synchronization with Multi-master replication, filtered synchronization, and transformation capabilities. [2] It is designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. [3]
Multi-master replication, a method of replication employed by databases to transfer data or changes to data across multiple computers Topics referred to by the same term This disambiguation page lists articles associated with the title Multimaster .
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.
Load balancing, however, sometimes uses data replication (especially multi-master replication) internally, to distribute its data among machines. Backup differs from replication in that the saved copy of data remains unchanged for a long period of time. [5] Replicas, on the other hand, undergo frequent updates and quickly lose any historical state.
In computer science, state machine replication (SMR) or state machine approach is a general method for implementing a fault-tolerant service by replicating servers and coordinating client interactions with server replicas. The approach also provides a framework for understanding and designing replication management protocols.
Earlier replication software that allowed similar read scaling normally relied on adding replication triggers to the master, increasing load. PostgreSQL includes built-in synchronous replication [ 37 ] that ensures that, for each write transaction, the master waits until at least one replica node has written the data to its transaction log.
