Amazon DynamoDB is a fully managed proprietary NoSQL database offered by Amazon.com as part of the Amazon Web Services portfolio. [2][3] DynamoDB offers a fast persistent key–value datastore with built-in support for replication, autoscaling, encryption at rest, and on-demand backup among other features. [4][5]

A document-oriented database is a specialized key-value store, which itself is another NoSQL database category. In a simple key-value store, the document content is opaque. A document-oriented database provides APIs or a query/update language that exposes the ability to query or update based on the internal structure in the document. This ...
Apache Cassandra. Apache Cassandra is a free and open-source, distributed, wide-column store, NoSQL, database management system designed to handle large amounts of data across multiple commodity servers, providing availability with no single point of failure.

Keyspace (distributed data store) A keyspace example with a number of column families. A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1][2] It is the outermost grouping of the data in the data store. [3] It resembles the schema concept in Relational database management systems. [4]
Oracle NoSQL Database is a client-server, sharded, shared-nothing system. The data in each shard are replicated on each of the nodes that comprise the shard. The major key for a record is hashed to identify the shard that the record belongs to. Oracle NoSQL Database is designed to support changing the number of shards dynamically in response to ...
