Fp chance for column level bloom filter

[Takenori Sato]

Hi,

I thought memory consumption of column level bloom filter will become a big
concern when a row becomes very wide like more than tens of millions of
columns.

But I read from source(1.0.7) that fp chance for column level bloom filter
is hard-coded as 0.160, which is very high. So seems not.

Is this correct?

Thanks,
Takenori
