WebThe Raft consensus algorithm is a commonly used leader-based consensus protocol where a “leader” handles the task of data updates and replication. Strongly-consistent distributed databases have standardized onto this protocol. Leaderless consensus protocols are harder to implement but have higher availability than leader-based protocols.

WebData Replication Methods The data replication strategy you choose is crucial as it impacts how and when your data is loaded from source to replica and how long it takes. An application whose database updates frequently wouldn’t want a data replication strategy that could take too long to reproduce the data in the replicas. WebIf a process reads the value of of a data item x, any successive read operation on x by that process will always return that same value or a more recent value. (Example: e-mail ) A data store that does not provide monotonic reads. A monotonic-read consistent data store WS(x i): write set = sequence of operations on x at node L i WebReplication exists primarily to offer data redundancy and high availability. We maintain the durability of data by keeping multiple copies or replicas of that data on physically isolated servers. That’s replication: the process of creating redundant data to streamline and safeguard data availability and durability. law and order svu theatre tricks cast

WebReplication If your data workload is primarily read-focused, replication increases availability and read performance while avoiding some of the complexity of database sharding. By simply spinning up additional copies of the database, read performance can be increased either through load balancing or through geo-located query routing.
