@Zoxc one thing I noticed this weekend is that we keep the original hash when we shard, which means that 5 bits at least of the hash are always the same within a single shard, have we checked that hashbrown is okay with that?
I know I've heard historically that hash quality is super important for the hashmap performance (particularly the one we're using)
I picked the bits which hashbrown uses last to use for sharding
sure, but the hash is still being used for the top-level selection of which element to use, right?
did we check that we're still getting a good distribution?
