Hey all, I would like to propose adding a new app_metadata field to both the FlightInfo and FlightEndpoint message types of the Arrow Flight protocol. There has been discussion of doing so for a while and has now been brought back up in regards to [1]. More specifically, this enables adding application defined metadata for FlightSQL (by way of FlightInfo) which can then be utilized to pass information such as QueryID, QueryCost, etc.
I've put up a PR to add this at [2]. The vote will be open for at least 24 hours: [ ] +1 Add these fields to the Arrow Flight RPC protocol [ ] +0 [ ] -1 Do not add these fields to the Arrow Flight RPC protocol because.... Thanks much! --Matt [1]: https://github.com/apache/arrow/issues/37635 [2]: https://github.com/apache/arrow/pull/37679
