---------------------------------------
Summary: S3Guard instrumentation to include cost of DynamoDB ops
as metric
Key: HADOOP-15034
URL: https://issues.apache.org/jira/browse/HADOOP-15034
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.0.0
Reporter: Steve Loughran
Priority: Minor
DynamoDB ops can return the cost of the operation in {{ConsumedCapacity}}
methods.
by switching to the API calls which include this in the results are used in
{{DynamoDBMetadataStore}}, then we could provide live/aggregate stats on IO
capacity used. This could aid in live monitoring S3Guard load, and help assess
the cost of queries
