Nosql Questions
The purpose of replication in NoSQL databases is to ensure high availability and fault tolerance. It involves creating multiple copies of data across different nodes or servers.
Replication ensures data availability by distributing the data across multiple nodes, allowing for redundancy. If one node fails or becomes unavailable, the data can still be accessed from other nodes. This redundancy also helps in load balancing, as requests can be distributed among the available nodes, preventing any single node from becoming overwhelmed with traffic. Additionally, replication allows for data to be geographically distributed, enabling better performance and reduced latency for users in different locations.
