             Summary: s3guard init and set-capacity to support DDB autoscaling
                 Key: HADOOP-15563
                 URL: https://issues.apache.org/jira/browse/HADOOP-15563
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.1.0
         Environment: To keep costs down on DDB, autoscaling is a key feature: you set the
max values and when idle, you don't get billed, *at the cost of delayed scale time and risk
of not getting the max value when AWS is busy*

It can be done from the AWS web UI, but not in the s3guard init and set-capacity calls

It can be done [through the API|https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.HowTo.SDK.html]

Usual issues then: wiring up, CLI params, testing. It'll be hard to test.
