Is it signifigantly slower to use a seahash HashSet in order to support streaming? |

The dedup function I implemented is a quite simple solution: it sorts the entries and removes the neighbors. I don't know how this compares to a hashing algorithm, in particular with But it sounds interesting. Why don't you just try and implement it and check the differences? |

I implemented a "dedup" module to remove duplicated rows from a CSV.
It first sorts the CSV before finding neighboring rows and keeping only those which are no duplicates.
It can be used with the
selectoption to remove rows only if the selected columns are duplicated.With the
--no-caseoption, it ignores the case when comparing the strings of the CSV.
