Steve Loughran commented on HADOOP-16118:
-----------------------------------------
the metastore scale tests are failing because throttling isn't detected any
more.
Proposed: Identify when store is PAYG and skip the scale tests. We know it will
scale to the limits of your AWS credit line and overall AZ load.

> S3Guard to support on-demand DDB tables
> ---------------------------------------
>
> Key: HADOOP-16118
> URL: https://issues.apache.org/jira/browse/HADOOP-16118
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Priority: Major
>
> AWS now supports [on demand DDB
> capacity|https://aws.amazon.com/blogs/aws/amazon-dynamodb-on-demand-no-capacity-planning-and-pay-per-request-pricing/]
>
> This has lowest cost and best scalability, so could be the default capacity.
> + add a new option to set-capacity.
> Will depend on an SDK update: created HADOOP-16117.
