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.
