I want to list the size of the different database and trying the function:

db.stats()

But, my developer team is worried over that this might have a huge impact of the system. Should I be worried?

How does this function detect the statistic information such as the size of the different databases. Or is it a better way to detect the size of the database that I can use, which has little or no performance impact ..

I want compress the data stored in column more efficient, because mydata is timeseries of stock or future price.
Most of them is similar, so I thought I could compress the price data(float, uint64, int) more efficient than zlib,like what infobright do.

Could any one tell me how to compress the column more efficient or could I get the blocks data type when I write the compress plug.
