HyperLogLog hash function

[yarosman]

Will it be better to apply hash function on elements before adding to hll or it doesn’t necessary ? And what the hash function does aerospike use ?

Currently, we do not provide an API to send pre-hashed values. So if you sent hashed values, they would be re-hashed on the server.

We use the MurmurHash3_x64_128.
