Question regarding bloom filters

[manish khandelwal <ma...@gmail.com>]

Hi All

I was reading about the read path. It says bloom filters are read from
memory. But bloom filters can become very large so they may occupy lot of
memory. So are all bloom filters loaded in memory on startup or are loaded
with read requests.

They’re loaded in (offheap) memory on startup. They do scale with data size, so sufficiently large data sets will need smaller (higher FP chance) bloom filters if they become memory constrained.
