Amazon Keyspaces (for Apache Cassandra) features

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra–compatible database service. With Amazon Keyspaces, you can run your Cassandra workloads on Amazon Web Services by using the same Cassandra application code and developer tools that you use today. You don’t have to provision, patch, or manage servers, and you don’t have to install, maintain, or operate software. Amazon Keyspaces is serverless, so you pay for only the resources you use and the service can automatically scale tables up and down in response to application traffic. You can build applications that serve thousands of requests per second with virtually unlimited throughput and storage.

Amazon Keyspaces is compatible with the open-source Cassandra CQL API, so you can migrate your existing Cassandra tables to Amazon Keyspaces while continuing to use your existing application code.

You can use existing Apache Cassandra 2.0–licensed drivers and developer tools with Amazon Keyspaces. Open-source Cassandra drivers are available for Java, Python, Ruby, .NET, Node.js, PHP, C++, and Perl.

With on-demand capacity mode, you do not have to overprovision throughput for unexpected peak workloads. Capacity is managed automatically, and you pay for only the resources you use. Learn more about on-demand capacity mode on the pricing page.

Provisioned capacity mode helps you optimize the price of throughput if you have predictable application traffic by enabling you to specify the number of reads and writes per second in advance that you expect your application to perform. You can use auto scaling to adjust your table’s capacity automatically in response to changes in application traffic to maintain performance without overprovisioning capacity. Learn more about provisioned capacity mode on the pricing page.

Use Time to Live (TTL) to set expiration times on rows and attributes in your Keyspaces tables, and automatically delete the records after they expire. Keyspaces TTL is fully managed, so you don't need to manage or provision additional read/write capacity. You also do not need to manage tombstones or low-level system operations such as compaction. Keyspaces deletes expired data automatically and transparently.

Amazon Keyspaces provides consistent single-digit-millisecond read and write performance at any scale, so you can build applications with low latency to provide a smooth user experience.

Amazon Keyspaces tables scale in response to actual application traffic, with virtually unlimited throughput and storage. There is no limit on the size of tables or the number of rows per table.

Amazon Keyspaces is integrated with Amazon CloudWatch. CloudWatch collects and processes data from Amazon Keyspaces into readable metrics, providing you with visibility into how your application is performing.

Amazon Keyspaces provides fully managed and highly available data storage. Your table data is replicated automatically three times across multiple Amazon Web Services Availability Zones for durability.

Amazon Keyspaces encrypts all customer data at rest by default. Encryption at rest enhances the security of your data by using encryption keys stored in Amazon Key Management Service.

Amazon Keyspaces is integrated with Amazon Identity and Access Management to help you manage access to your tables and data.

Amazon Keyspaces supports secure networking by using TLS. You can use Amazon PrivateLink to provide secure connectivity between your resources in Amazon Keyspaces and Amazon Virtual Private Cloud (Amazon VPC).

Point-in-time recovery (PITR) helps protect your Amazon Keyspaces tables from accidental write and delete operations. PITR provides continuous backups of your Amazon Keyspaces table data, and you can restore that table to any second during the preceding 35 days. You can enable PITR or initiate backup and restore operations with a few clicks in the Amazon Web Services Management Console or a single API call.

Amazon Keyspaces offers an availability SLA of 99.99% within an Amazon Web Services Region, providing you with a strong availability commitment and no scheduled downtime.
