A global state management service manages replication in a distributed system. A distributed system can have several replica groups. The global state management service manages state associated with each replica group. Data replication is implemented without implementing an instance of a state machine on...

Data Replication in a Distributed System: A Performance Study Investigates the performance issues of data replication in a loosely-coupled distributed database system, where a set of database servers are connected via a network. A database replication scheme called "replication with divergence", wh....
If a table to be synchronized is a replication table without a primary key in GaussDB, the task will fail. Precautions To ensure tasks can run normally, DRS provides automatic pre-check. Before starting a DRS task, DRS checks the configurations and conditions of the source and destination ...
To forcibly stop a synchronization task, you need to manually delete the replication slots that may remain in the source database. For details, see Forcibly Stopping Synchronization of GaussDB Distributed. To forcibly stop a synchronization task, delete the temporary tables without primary keys whose...
The concepts of transaction and of data consistency are defined for a distributed system. The cases of partitioned data, where fragments of a file are stored at multiple nodes, and replicated data, where a file is replicated at several nodes, are discussed. It is argued that the distribution...
Data Sharing System In subject area: Computer Science A data sharing system refers to a system where multiple machines or processes can access the same database or stable storage devices, enabling the synchronization of access to shared data. It allows for replication of the server but not the ...
METHOD AND SYSTEM OF STATELESS DATA REPLICATION IN A DISTRIBUTED DATABASE SYSTEM In one exemplary embodiment, a method includes the step of executing, with at least one processor, a main database node server in a source-database node of a source-database cluster. The main database node serve...
Replication schemes are the operations and tasks required to perform data replication. The three main data replication schemes are full replication, partial replication and no replication. Withfull replication,a primary database is copied in its entirety to every site in the distributed system. This ...
