New update??? Not possible create 1billion bloom... #45

Closed pianistprogram closed 1 year ago

pianistprogram commented 3 years ago

Is it possible to release a new update with the ability to save the Bloom filter from RAM to the hard disk, with the ability to combine different filters into one? I can't create a filter with 1 billion records! And in conclusion, thank you for your efforts!

Currrently it is not possible to persist the filter that's initialised in memory to disk.

However you might have luck with using Base64 serialization in that case.

For 1 billion records you probably need to check the accuracy parameters, as well as limits on the hashes (which is internal).
