David Li commented on ARROW-5143:
---------------------------------
The Flight integration tests still fail on the dictionary batch, even
C++-to-C++.
The gRPC error is "grpc-message: Dictionary with id 0 not found". (Aside: gRPC
still doesn't report this to us - it just aborts. May need to send an issue
upstream if we can make a minimal reproduction.)
The (relevant part of) the server backtrace is:
