# Welcome


Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra-compatible database service. Amazon Keyspaces makes it easy to migrate, run, and scale Cassandra workloads in the AWS Cloud. With just a few clicks on the AWS Management Console or a few lines of code, you can create keyspaces and tables in Amazon Keyspaces, without deploying any infrastructure or installing software. 

In addition to supporting Cassandra Query Language (CQL) requests via open-source Cassandra drivers, Amazon Keyspaces supports data definition language (DDL) operations to manage keyspaces and tables using the AWS SDK and AWS CLI, as well as infrastructure as code (IaC) services and tools such as AWS CloudFormation and Terraform. This API reference describes the supported DDL operations in detail.

For the list of all supported CQL APIs, see [Supported Cassandra APIs, operations, and data types in Amazon Keyspaces](https://docs.aws.amazon.com/keyspaces/latest/devguide/cassandra-apis.html) in the *Amazon Keyspaces Developer Guide*.

To learn how Amazon Keyspaces API actions are recorded with AWS CloudTrail, see [Amazon Keyspaces information in CloudTrail](https://docs.aws.amazon.com/keyspaces/latest/devguide/logging-using-cloudtrail.html#service-name-info-in-cloudtrail) in the *Amazon Keyspaces Developer Guide*.

For more information about AWS APIs, for example how to implement retry logic or how to sign AWS API requests, see [AWS APIs](https://docs.aws.amazon.com/general/latest/gr/aws-apis.html) in the *General Reference*.
