Detailed explanation-1: -Types of NoSQL Databases. Key-value: Key-value databases are highly partitionable and allow horizontal scaling at scales that other types of databases cannot achieve.
Detailed explanation-2: -NoSQL describes a horizontally scalable, non-relational database with built-in replication support. Applications interact with the database through a simple API, and the data is stored in a schema-free repository as large files or data blocks.
Detailed explanation-3: -NoSQL databases are scalable horizontally, meaning that they use multiple nodes in a cluster to handle increased workloads. This allows data architects to simply scale them by supplementing clusters with additional servers.
Detailed explanation-4: -What is Horizontal Scaling? Horizontal scaling, also known as scale-out, refers to bringing on additional nodes to share the load. This is difficult with relational databases due to the difficulty in spreading out related data across nodes.
Detailed explanation-5: -The type of scaling supported by NoSQL is Horizontal.
