Steve Loughran commented on HADOOP-9565:
----------------------------------------
Simplest just to start with a marker interface,
# consistency rules vary across S3 clusters, so an enum couldn't even be
constant for an implementation -would need to know the endpoint. Safest to say
"assume eventual consistency and non atomic operations"
# Put and copy may not be supported by all, should really go into their own
interfaces.
> Add a Blobstore interface to add to blobstore FileSystems

> Key: HADOOP-9565
> URL: https://issues.apache.org/jira/browse/HADOOP-9565
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs
> Affects Versions: 2.0.4-alpha
> Reporter: Steve Loughran
> Priority: Minor
>
> We can make the fact that some {{FileSystem}} implementations are really
> blobstores, with different atomicity and consistency guarantees, by adding a
> {{Blobstore}} interface to add to them.
> This could also be a place to add a {{Copy(Path,Path)}} method, assuming that
> all blobstores implement at server-side copy operation as a substitute for
> rename.
