> It looks like most compute functions that take an array-like can accept a ChunkedArray as well. One exception to that appears to be replace_with_mask which seems to seg fault when the array-like is a chunked array. Here is an example:
>  
>  
> {code:java}
> import pyarrow as pa 
> import pyarrow.compute as pc 
> ca = pa.chunked_array([[1, 2], [3, 4]]) 
> mask = [False, True, False, True] 
> # works (when we first combine chunks into a single array) 
> a_new = pc.replace_with_mask(ca.combine_chunks(), mask, 0) 
> # seg fault (if we try to pass the chunked array) 
> ca_new = pc.replace_with_mask(ca, mask, 0){code}
>
