Pranith,
                 Thanks. Does it mean that a given file can be written by only
one client at a time. If multiple clients try to access the file in write mode,
does it lead to any kind of data inconsistencies.

We only tested it for single writer cases such as VM usecases. We need to bring
in transaction framework for sharding to work with multiple writers.


Thanks and Regards,

It is never been tested. That said, I don't see any missing pieces that we
know of for it to work. Please note that sharding works only for single writer
cases at the moment. Do let us know if you find any problems and we will fix
them.

Hi,
      Are there any known negatives of enabling shard on EC. Is this a
recommended configuration?.

Thanks and Regards,

+Krutika

Krutika started work on this. But it is very long term. Not a simple thing
to do.
