Awesome -- I polished up the PR and I think it is now ready to review. Hopefully we'll get it merged in (assuming there are no objections) in the next few days

Hi Anil,

 I don't know of any specific plans to make DataFrame Send+Sync, but I gave it a quick shot: https://github.com/apache/arrow/pull/9406

And it seems to work -- if this is the change you are looking for? If so I can polish up that PR and get it ready for review and hopefully merged soon

Hi,
I am new to rust so my question can be nonsense so thank you for your patience in advance. I am trying implement a small single node query service and it will return its data over grpc(not flight). When i try to use execution context and dataframe api behind a tonic service,compiler gives error:
the trait Sync is not implemented for dyn datafusion::dataframe::DataFrame
as i understand all futures should be sync+send for tonic and currently dataframe api is not sync+send. Are there any plans to make it sync+send? Or should i look for other ways to implement it?Currently i am using this method

Best Regards...
