devel/py-cykhash: Cython equivalent to khash-sets/maps
Cykhash is a cython equivalent to khash-sets/maps, efficient
implementation of isin and unique
Benefits:
Brings functionality of khash to Python and Cython and can be used
seamlessly in numpy or pandas.
Numpy's world is lacking the concept of a (hash-)set. This
shortcoming is fixed and efficient (memory- and speedwise compared
to pandas') unique and isin are implemented.
Python-set/dict have big memory-footprint. For some datatypes the
overhead can be reduced by using khash by factor 4-8.
