> I believe JVM doesn't care about this Allocation parameter Indeed, and that is the problem :sweat_smile: So for example when receiving data over the C Data interface, e.g. for interop with arrow-cpp or pyarrow, we construct an FFI_ArrowArray, which then gets passed as the `Allocation` parameter - https://github.com/apache/arrow-rs/blob/master/arrow-array/src/ffi.rs#L239. This ensures that the memory is not freed or mutated by the external process until we are done with it. -- This is an automated message from the Apache Git Service.
