Provisioned capacity mode helps you optimize the price of throughput if you have predictable application traffic and can forecast capacity requirements in advance. Managing Cassandra tables yourself can be time consuming and expensive. Write operations on static data are metered separately from non-static data. You can increase and decrease the provisioned capacity for your table automatically in response to actual application traffic by enabling auto scaling. For example, to read a row with 10 KB of data requires 3 RRUs using LOCAL_QUORUM consistency or 1.5 RRUs using LOCAL_ONE consistency. Migration.
