---------------------------------------
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.
