Is Google Guava Bloom Filter thread safe?

Is the guava bloom filter in 18.0 thread safe. On other words, can I have multiple threads share a Bloom Filter instance and use myBloomInstance.mightContain and myBloomInstance.put concurrently. Thank you for your help

No, you must synchronize.

You can split in into a few parts if you need concurrency. There's com.google.common.util.concurrent.Striped which makes it pretty easy.

And as always, you can fill it and only read it in another thread, assuming that you do a save publication.

Update

The BloomFilter is thread-safe in the current Guava version: https://github.com/google/guava/commit/6092a4a8b1087f92d0c3169b9e96d53c54ca95c4
