what does the <bucket_size> param used for in feature_column.py?

i cannot find any hash function or other usage...

  1. category_column only accept slot/int/ID features
  2. or support string categorical feature to be hashed by bucket_size?

please convert all features into uint64 first, you can choose hash function like murmurhash do that.
