Converts each string in the input Tensor to its hash mod by a number of buckets.
The hash function is deterministic on the content of the string within the process. The hash function is a keyed hash function, where attribute
key defines the key of the hash function.
key is an array of 2 elements.
A strong hash is important when inputs may be malicious, e.g. URLs with additional components. Adversaries could try to make their inputs hash to the same bucket for a denial-of-service attack or to skew the results. A strong hash prevents this by making it difficult, if not infeasible, to compute inputs that hash to the same bucket. This comes at a cost of roughly 4x higher compute time than
- scope: A Scope object
- input: The strings to assign a hash bucket.
- num_buckets: The number of buckets.
- key: The key for the keyed hash function passed as a list of two uint64 elements.
