Replication in computing refers to maintaining multiple copies of data, processes, or resources to ensure consistency across redundant components. This fundamental technique spans databases, file systems, and distributed systems, serving to improve availability, fault-tolerance, accessibility, and performance. [1]
Distributed objects are used in Java RMI. CORBA lets one build distributed mixed object systems. DCOM is a framework for distributed objects on the Microsoft platform. DDObjects is a framework for distributed objects using Borland Delphi. Jt is a framework for distributed components using a messaging paradigm. JavaSpaces is a Sun specification ...
Embedded database supporting efficient, distributed management of C++ and Java objects. Avoids the complexities and limitations of ORM products such as Hibernate by storing objects directly with their relationships intact. Uses a page-based mapping system for fast locking and efficient, distributed, client-side caching. ODABA: 12.3.0 (August 2013)
Riak is a distributed NoSQL key-value data store based on CRDTs. [29] League of Legends uses the Riak CRDT implementation for its in-game chat system, which handles 7.5 million concurrent users and 11,000 messages per second. [30] Bet365 stores hundreds of megabytes of data in the Riak implementation of OR-Set. [31]
Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
Eventual consistency, also called optimistic replication, [2] is widely deployed in distributed systems and has origins in early mobile computing projects. [3] A system that has achieved eventual consistency is often said to have converged, or achieved replica convergence. [4]
Consistency models are used in distributed systems like distributed shared memory systems or distributed data stores (such as filesystems, databases, optimistic replication systems or web caching). Consistency is different from coherence, which occurs in systems that are cached or cache-less, and is consistency of data with respect to all ...
In fault-tolerant systems, distributed databases must be able to cope with the loss or corruption of (part of) their data. The first step is usually replication, which involves making multiple copies of the data and keeping them all up to date as changes are made. However, it is then necessary to decide which copy to rely on when loss or ...
