Hi Ted and Vladimir, thanks!
I was thinking if using index is a good idea. My scan/get criteria is
something like "get all rows I inserted since end of yesterday". I may
have to use MapReduce + timeRange filter.
Lars and all, I will try to report back some performance data later.
Thanks for the help from you all.

Subject: Re: larger HFile block size for very wide row?
bq. table:family2 holds only row keys (no data) from table:family1.
You can designate family2 as essential column family so that family1 is
brought into heap when needed.
