TableResult and getSubTable().
I think hbase need to make a TableResult and getSubTable() by range.

You don't need to take a skeptical approach; The discussion can be
resolved itself into an argument.
Please do discuss with hbase members. :)

You're talking about a projection of sorts, right?
Certainly I think it's doable. However, I would like to know why
you'd want to do this instead of just using scanners the way they are
now. I would go so far as saying that this IS what scanners do now.
The only difference that I can think of would be returning more than
one row at a time.
Am I missing any features you would like to exist? Would something in
the client API make it very different? How would you address the
memory/performance issues that would arise?

Yo, Do you think it's possible?
I just mean the formed table by selecting certain rows and columns (or
version) from a big table.

What would getSubTable do? Retrieve a whole range of rows at once
(unlike a scanner, which retrieves a range of rows one at a time)?
