Cache key is fingerprint

It seems to me that when working with gotomic hash, we use 64-bit fingerprint of pred, source UID and never check for collision? In practice, this is more than the number of predicates, and remember that we choose not to fingerprint the predicate?

Because gotomic hash is working on a local data set. Not across the entire cluster.

Thanks for the quick reply. Sounds good to me. For final production, we should probably still check? But it is ok to leave out now.

Yeah, would make sense to check them. Though, depends upon the cost of checking it.
