Amazon MSK can now automatically expand cluster storage
Amazon Managed Streaming for Apache Kafka (Amazon MSK) can now automatically expand storage of a MSK cluster, making it easier for you to continuously right-size the storage provisioned. Using Application Auto Scaling policies you set and control both the target cluster storage utilization threshold and a maximum storage limit. These policies will automatically trigger cluster-wide storage expansion by a required amount when the storage utilization threshold is exceeded. Automatic storage expansion is offered at no additional cost and can be used in all AWS regions where MSK is available excluding AWS Europe (Milan).
