Amazon Keyspaces
Amazon Keyspaces (for Apache Cassandra) is a serverless Amazon Web Services service used to manage Apache Cassandra-compatible databases without managing servers.
Key points
- Runs existing Cassandra workloads on AWS without making any changes to the Cassandra application code.
- Implements the Apache Cassandra Query Language (CQL) API, so existing CQL statements and Cassandra drivers work unchanged.
- Eliminates operational burdens such as scaling, patching, updates, server maintenance, and provisioning.
- High availability and durability from maintaining three copies of data across multiple Availability Zones.
- Tables scale automatically; supports thousands of requests with single-digit-millisecond response latency.
- Continuously backs up hundreds of terabytes of table data, with point-in-time recovery for the next 35 days.
- Throughput capacity modes:
- On-demand — charges applied for the reads and writes actually performed.
- Provisioned — charges minimized by specifying the number of reads and writes per second in advance.
