Subject [jira] [Commented] (HADOOP-13345) S3Guard: Improved Consistency for S3A
Date Thu, 09 Feb 2017 14:26:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15859586#comment-15859586

Steve Loughran commented on HADOOP-13345:
-----------------------------------------

I should add to aaron with 

# the in-memory one really, really is for testing only. 
# it won't be throttling per-se, more than when you get API calls rejected,  the client will
back off. See HADOOP-13904.

I like your thoughts about HBase; there's no obvious reason why this won't work (though you
need to persist it somehow). For now though, Dynamo is what we target, so we can just use
something that AWS keeps up. It helps for dev & test as we don't need to bring up miniHbase
clusters.

> 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.
