Re: how to maintain versioning in D4M schema?

[shweta.agrawal]

If I append timestamp on rowid. The id which acts as a node will act as 
a different entity.
How this will be maintained?

Thanks

Hi Shweta,

You have lots of options.  You could append or prepend a timestamp to 
the rowid or column qualifier.  When prepending to the rowid, you may 
want to reverse the timestamp in order to better shard your data (that 
is, prevent all updates at a particular time from going to a single 
tablet server), at the expense of not being able to do range queries 
on time periods.  You could also disable or relax the 
VersioningIterator.  It depends on what you want to do.

    Hi,

    I have my data stored in D4M style. I also want to maintain
    versions of different value on the basis of time.  As in D4M
    style  data is only in rowid and colQualifier only.

    Is there any way to achieve versioning in D4M schema?

    Thanks
