Amazon Managed Cassandra Service quota information is now available through Service Quotas
Amazon Managed Apache Cassandra Service (MCS), a scalable, highly available, and managed Apache Cassandra–compatible database service, now enables you to retrieve service quota information through Service Quotas.
Service Quotas helps you to view and manage service quota information centrally for your AWS services. Now, you can use the Service Quotas console, AWS Command Line Interface, and AWS SDK to view service quota information for Amazon MCS, such as the maximum on-demand read and write operations you can perform on a table.
There is no additional cost to view Amazon MCS quota information in Service Quotas. Amazon MCS is available in preview in the US East (N. Virginia), US East (Ohio), EU (Stockholm), Asia Pacific (Tokyo), and Asia Pacific (Singapore) Regions.
For more information, see Quotas in the Amazon MCS Developer Guide.
