[jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for
S3A
[ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15468732#comment-15468732 ]
Chris Nauroth commented on HADOOP-13345:
----------------------------------------
Yes, on further reflection, I agree that much of the aspects of policy that I laid out earlier (and their corresponding JIRA sub-tasks) can be simplified. Aaron's last 2 comments look like a step in the right direction. I suggest that we proceed toward implementing what the design doc describes in "Policy C: On-​Demand Source of Truth". A small number of properties like Aaron described might influence the exact behavior. Beyond that, a more complex notion of policy might turn out to be overkill. Some of those JIRA sub-tasks might just get closed as invalid.
My immediate next step will be to review the work Aaron did on HADOOP-13448 in my absence.

> This issue proposes S3Guard, a new feature of S3A, to provide an option for a stronger consistency model than what is currently offered. The solution coordinates with a strongly consistent external store to resolve inconsistencies caused by the S3 eventual consistency model.
