Tables can scale up and down automatically, and you can optimize the cost of reads and writes based on your application’s traffic patterns by choosing either on-demand or provisioned capacity mode. You can forecast capacity requirements to optimize price. pattern might vary between 5,000 and 10,000 LOCAL_QUORUM reads per KB, you require 2 WCUs to sustain one write request per second. Amazon Keyspaces is serverless, so you pay for only the resources you use and the service can automatically scale tables up and down in response to application traffic.
