Need fast lookup for block lists

[jmeaster30]

I want the ability to download a file of bad domain names and be able to block domains if they are in that file

This would require some sort of fast lookup data structure.

• BloomFilter
  • Probabilistic (possibly in or definitely not)
  • Can't remove elements from set
  • Complicated
  • Space-Efficient
  • Sounds fun though
• HashSet
  • O(1) assuming hashing is constant time
  • Binary search list of integers?
  • Don't care about the time for adding (as long as updating doesn't affect other threads reading from it) so we can still do lookups in other threads

We COULD make the database handle it

Turns out the bloom filter is NOT complicated. I have an implementation but want to do more research into other options
