David Li commented on ARROW-12884:
----------------------------------
This may also be redundant with the underlying transport (e.g. gRPC with TLS),
if the goal is solely to ensure that the data wasn't corrupted on the wire.
Otherwise I agree with Antoine that it makes more sense as part of IPC.

> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Wes McKinney
> Priority: Major
>
> Currently, there is not a built-in mechanism to allow for data integrity
> checks for FlightData messages. This issue is to discuss and see if there may
> be a way to add this to Flight without making things more complicated for the
