Having Problemns While Using Dask Map_partitions With String Matching Algorithm

I'm having some probems apllying a text search algorithm with parallelized dask insfrastructure. I'm tryng to find the best match for 40,000 stirngs in a series object against a 4

Solution 1:

Doing the MCVE I realized that it was a naive syntax problem: I can't use the map_partitions on a dask dataframe without specifying the column that im using even if there is only one column. So I should had used sd[0].map_partitions insted of sd.map_partitions
