Michael Novitsky commented on ARROW-8679:
-----------------------------------------

[~jorisvandenbossche] Hi Joris, we are dealing with data that is sparse in its 
nature (contains many nans) and we currently have memory problems when dealing 
with a big Dataframe . We can't use scipy sparse matrices since they support 
compression on zeros only and not nans and we want the data to be sparse in the 
whole flow - dataframe->pyarrow->plasma store. 

Support for conversion to one of the sparse tensors in pyarrow could indeed be 
added - can you please point me to the part where this conversion is happening?

> I've seen that Pandas sparse series was not supported in pyarrow since it was 
> planned to be deprecated.  In Pandas 1.0.1 they released a stable version of 
> sparse array and as far as I know it is not planned to be deprecated anymore. 
> Are you planning to support sparse series in next versions of pyarrow ?
