With Amazon NoSQL databases, you get high performance, enterprise-grade security, automatic, and instant scalability. The following table lists some of the AWS managed NoSQL database services offered, and their key characteristics: *Table 1 — AWS database service comparison * | AWS database service | Use cases | Strengths | Security | Performance | Cross-Region resiliency | | --- | --- | --- | --- | --- | --- | | Amazon DocumentDB (with MongoDB compatibility)**\***[See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | User profile/personalization, catalogs, mobile, and content management, retail and marketing (for example, tracking customers who purchase similar items) | Flexible schema and indexing, ad hoc queries on any attributes, including nested attributes | Capability to enable data encryption at rest and in transit | Millions of requests per second with millisecond latency | DocumentDB Global clusters | | Amazon DynamoDB**\*** [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | Encrypts all data at rest by default, row/column level security | Single digit millisecond at any scale, In-memory acceleration with DynamoDB (DAX) for low latency access to eventually consistent data | Global tables | | Amazon Keyspaces (for Apache Cassandra)[See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | High scalable apps for: [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | Single digit millisecond response at any scale | [Multi-Region Replication](https://docs.aws.amazon.com/keyspaces/latest/devguide/multiRegion-replication.html) | | Amazon Neptune**\*** [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | Capability to enable data encryption at rest and in transit | High throughput, low latency | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | | Amazon Timestream**\*** [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | [See the AWS documentation website for more details](http://docs.aws.amazon.com/whitepapers/latest/choosing-an-aws-nosql-database/understanding-amazon-nosql-data-stores.html) | Analytics over time series data | Encrypts all data by default | Capable of ingesting trillions of events daily.
