For the overload of replace in libcudf where input/target/repl are columns, there isn't a maxrepl arg. about cudf HOT 6 OPEN

The documentation provides an example on how it works
https://docs.rapids.ai/api/libcudf/stable/group__strings__replace#ga59aaccc6c1adc602454becd5c8755d84
Do you have a suggestion for the name? replace_multiple ?

To provide more context, in Cython when you have fused types, the number of arguments stays constant, so you can't have the situation like in C++, where you have an overload with one less argument or something like that.

Supporting this in libcudf never really made sense since it would be confusing to know where the max was applied.
Is it per target or per repl or both? Should there be a column of max values?
Also, I don't know when it would be used and no one has asked for the feature so I would likely mark this a "won't fix".
We could certainly change the name of the API if that helps.

That makes sense, I think I misunderstood what replace did.

Renaming this might help.
Personally, I always confuse this method as doing a vectorized replace, where there's a different target and replacement value for every string value in the column.

Maybe that's just me though.

Yep that sounds good to me.
