Bloom filter hash functions

[南京大学软件学院薛恺丰 <82...@qq.com>]

Hi~
I found that we can use Murmur hash to improve our hash performance. In real data, the distribution of hash bit can improve from 40% coverage to 55% coverage and cause only minor impact on write performance.

Hi,

Good! If so, Murmur hash could be used.

BTW, it's better to reply to a previous mail instead of opening a new theme.

Thanks,
