Re: MD5 in the read path
In some installations, it's used for hashing the partition key to find the
host ( RandomPartitioner )
It's used for prepared statement IDs
It's used for hashing the data for reads to know if the data matches on all
We don't use CRC because conflicts would be really bad. There's probably
something in the middle that's slightly faster than md5 without the
drawbacks of crc32
