Question

I was using BloomFilter in guava v.11.0.1 and it seems like I am getting an exception when my insertion is large. I tried at 10 million with 0.001 fpp, and it failed.

I think at least it should support that many insertions with such a high fpp, shouldn’t it?

Answer 1

Sorry about this, I’m the culprit 🙂

Hopefully we will be able to push the next version soon. Not the time to mention this, but there is an upside to this accident: it means we can definitely kill the current serial form of BF and its related supporting code (which was an accident itself), which I’m trying to fix for a month now – incidentally the fix to that also fixes this problem.

Edit: more information here (and in Louis’ filed issue)
