Hi everyone,
I was reading bigtable paper these days.
And from the paper, I have a little question.


"Each METADATA row stores approximately 1KB of data in memory. With a modest 
limit of 128 MB 
METADATA tablets, our three-level location scheme is sufficient to address 2^34 
tablets."


I am confusing because 2^10 * 2^7 = 2^17
How could it store 2^34 tablets?
