@NguyenHoangSon96 is there a real problem or just a theoretical discussion? `ReadableBuffer` is an internal type, it should not be used from other projects.

@NguyenHoangSon96 As a workaround you can try setting the properties/environment variables mentioned in https://github.com/apache/arrow-java/blob/96156ccc2bf933c75c852ca7c04418a61f87defd/flight/flight-core/src/main/java/org/apache/arrow/flight/ArrowMessage.java#L70 They access internal classes (with reflection) in https://github.com/apache/arrow-java/blob/main/flight/flight-core/src/main/java/org/apache/arrow/flight/grpc/GetReadableBuffer.java - not sure if that's an expected use-case.

`ReadableBuffer` was introduce long ago, probably there were some plans for such a method back then. As of now, it's not used in grpc-java. We can agree the current state...
