Amazon Keyspaces now helps you monitor table storage costs through Amazon CloudWatch

[Amazon Keyspaces (for Apache Cassandra)](/keyspaces/), a scalable, highly available, and fully managed Apache Cassandra-compatible database service, now helps you monitor your table-level storage costs through [Amazon CloudWatch](/cloudwatch/). Amazon Keyspaces helps you run Cassandra workloads more easily by using a fully managed and serverless database service. With Amazon Keyspaces, you don’t need to provision storage upfront and you [pay for only the storage that you use](https://aws.amazon.com/keyspaces/pricing/#Storage). Now, you can use the **BillableTableSizeInBytes** CloudWatch metric to monitor and track your table storage costs over time. The **BillableTableSizeInBytes** metric provides the billable storage size of a table by summing up the [encoded size](https://docs.aws.amazon.com/keyspaces/latest/devguide/working-with-rows.html#calculating-row-size) of all the rows in the table. See [Amazon CloudWatch pricing](/cloudwatch/pricing/) for information about the pricing of CloudWatch metrics. The Amazon Keyspaces billable storage size CloudWatch metric is available in all AWS Regions where [AWS offers Amazon Keyspaces](/about-aws/global-infrastructure/regional-product-services/). For more information, see [Monitoring Amazon Keyspaces with Amazon CloudWatch](https://docs.aws.amazon.com/keyspaces/latest/devguide/monitoring-cloudwatch.html).
