Provision storage throughput for brokers in a Amazon MSK cluster
Amazon MSK brokers persist data on storage volumes. Storage I/O is consumed when producers write to the cluster, when data is replicated between brokers, and when consumers read data that isn't in memory. The volume storage throughput is the rate at which data can be written into and read from a storage volume. Provisioned storage throughput is the ability to specify that rate for the brokers in your cluster.
You can specify the provisioned throughput rate in MiB per second for clusters whose
brokers are of size kafka.m5.4xlarge
or larger and if the storage
volume is 10 GiB or greater. It is possible to specify provisioned throughput during
cluster creation. You can also enable or disable provisioned throughput for a
cluster that is in the ACTIVE
state.
