Thanks DuyHai,
I think the trouble of bloom filter on all row keys column names is
memory usage. However, if a CF has only hundreds of columns per row, the
number of total columns will be much fewer, so the bloom filter is possible
for this condition, right? Is there a good way to adjust bloom

bloom filter on column key? Is it a good idea to offer a table property

Hi all,
After reading some docs, I find that bloom filter is built on row keys, not
on column key. Can anyone tell me what is considered for not building bloom
filter on column key? Is it a good idea to offer a table property option
between row key and primary key for what boolm filter is built
Hello Philo
Building bloom filter for column names (what you call column key) is
technically possible but very expensive in term of memory usage.
The approximate formula to calculate space required by bloom filter can
be found on slide 27 here:
