Regards sponsoring this issue, would suggest more than Ted Yu as volunteer is needed if serious
about getting this in to 0.95/0.96 (I am working on 0.95 testing and last issues so do not
have bandwidth to help here)
{quote}
[~enis] do you have any bandwidth? Since you've shown interested earlier :-)

{quote}
IMO, the time for new features in 0.95 is loooooonnnnnnggggggg past so hard to justify holding
up release for this.
{quote}
Looking at the comments there aren't any major issues apart from the delimiter. The namespace
affected tests are passing.

Lets get a feature branch going. I can help set up apache build of the branch or do it over
on andrew's ec2... so can get some test runs going.
{quote}
Either sounds fine to me.

Need to work out the dot problem. Can we do the search in two places as is suggested over
on the list (internally, Elliott has suggested how to implement); i.e. only new tables go
into namespace? (Cannot gauge the migration problem till know how this plays out)
{quote}
Working on my existing patch we can try out elliot's suggestion which would essentially require
the new interfaces

{quote}
If this goes into 0.95, table grouping can be done after 0.95 as CPs? Not clear after reading
above.
{quote}
Yep it's possible. Though the patch will need some small changes in assignment manager and
LoadBalancer interface, etc. Better to get those in soon if we're in a hurry. I can separate
those out as a separate patch as well?

{quote}
Breaking patch into pieces will help yes, especially ones that collect into one place our
interaction with filesystem (see Matteo's recent work).
{quote}
It's gonna be hard, will give this a try.
