Concurrent creation and merging? #35

Do I understand your work correctly that it's not possible to combine multiple filters into one?

We are having a partitioned vector, which is prepared in multiple threads. We currently build BloomFilters and and them in the end. Is something similar possible with the xor of binary fuse filters?

You compute a filter over the union of the result using Bloom filters. I don’t see how that’s possible using xor or binary fuse filters.

Ok, thanks for the quick answer!
