Amazon Managed Apache Cassandra Service (MCS), a scalable, highly available, and managed Apache Cassandra–compatible database service, now helps you coordinate increments and decrements to column values by using counters.
Counters make it easier to coordinate increments and decrements to column values in distributed systems, or in scenarios where increments happen rapidly. For example, you can use counters to track the number of entries in a log file or the number of times a post has been viewed on a social network. Using counters ensures that updates are serialized and multiple clients can update the same column value without overwriting each other.
There is no additional cost to use counters, and support for counters is available in all AWS Regions where Amazon Managed Cassandra Service is offered.
For more information, see the “Counters” section under Data Types in the Amazon MCS Developer Guide.
