[GitHub] [arrow-rs] jinmingjian opened a new issue #272: Arrow does not support computing kernel for Decimal type

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   My project is using DataFusion as a query engine. I am surprising to find DF does not support agg on Decimal. Further looking shows, the more foundational problem is Arrow does not support computing kernel for Decimal type.  Not sure am I right? or I make some misunderstanding?

   Ran into this too ... and after I already spent few weeks patching Decimal support in Apache Flink.
   A large portion of the datasets we're dealing with are financial, so this is a serious gap in functionality.
   Decimal type deserves more love :)

   You are right, it is still not implemented, and it is a valid feature to implement. 👍
