   Hi .. I am trying to compute several aggregate functions on one or more columns on a large dataset which doesnt fit into memory. What is the suggested approach to doing these computations in single pass?

   Hi @svittapu, 
   We prefer to have conversation like this on the [user@](https://arrow.apache.org/community/) mailing list.  If you do start a thread there including what the target language is could be useful, and more specifics about the problem.  This is a very generalized/vague problem statement.
   
   Thanks.
