Hi, I was able to connect using the java demo example to the endpoint , I noticed there is no example on how to produce arrow data , is the endpoint also open to put requests ? Is there an example how to do this in java ?

@dsebban Are you trying to do a CTAS to arrow format? Dremio currently does CTAS only into PARQUET

We already produce our data as arrow in our backend , I want to use flight to send it to dreamio so I can fetch it later by subscribing to dreamio endpoints. Is this usecase supported ?

@dsebban Currently Dremio cannot read ARROW as a file format, although query results are written in arrow and Dremio internally uses ARROW a lot
