A distributed database is a database that is not restricted to a single system and is dispersed over numerous places, such as multiple computers or a network of computers. A distributed database system is made up of several locations with no physical components in common. This may be necessary if a database has to be viewed by a large number of people all over the world. It must be administered in such a way that it appears to users as a single database. Apache Ignite, Apache Cassandra, Apache HBase, Couchbase Server, Amazon Simple DB, Cluster point, and Foundation DB are some examples of distributed databases. Apache Ignite excels at storing and processing massive amounts of data across several nodes in a cluster. Local users may maintain and access data in local databases, while global users can get a global picture of the data thanks to distributed databases. In centralised database systems, if the system has to be expanded to additional locations or units, the activity necessitates significant effort and interruption of current operations. In distributed databases, on the other hand, the process is merely moving additional computers and local data to the new location and then connecting them to the distributed system, with no interruption in present operations.
